Limit Cyclomatic Complexity (complexity)
Cyclomatic complexity measures the number of linearly independent paths through a program's source code. This rule allows setting a cyclomatic complexity threshold.
function a(x) {
if (true) {
return x; // 1st path
} else if (false) {
return x+1; // 2nd path
} else {
return 4; // 3rd path
}
}
Rule Details
This rule is aimed at reducing code complexity by capping the amount of cyclomatic complexity allowed in a program. As such, it will warn when the cyclomatic complexity crosses the configured threshold (default is 20
).
Examples of incorrect code for a maximum of 2:
/*eslint complexity: ["error", 2]*/
function a(x) {
if (true) {
return x;
} else if (false) {
return x+1;
} else {
return 4; // 3rd path
}
}
Examples of correct code for a maximum of 2:
/*eslint complexity: ["error", 2]*/
function a(x) {
if (true) {
return x;
} else {
return 4;
}
}
Options
Optionally, you may specify a max
object property:
"complexity": ["error", 2]
is equivalent to
"complexity": ["error", { "max": 2 }]
Deprecated: the object property maximum
is deprecated. Please use the property max
instead.
When Not To Use It
If you can't determine an appropriate complexity limit for your code, then it's best to disable this rule.

Limit Cyclomatic Complexity (complexity)
Cyclomatic complexity measures the number of linearly independent paths through a program's source code. This rule allows setting a cyclomatic complexity threshold.
function a(x) {
if (true) {
return x; // 1st path
} else if (false) {
return x+1; // 2nd path
} else {
return 4; // 3rd path
}
}
Rule Details
This rule is aimed at reducing code complexity by capping the amount of cyclomatic complexity allowed in a program. As such, it will warn when the cyclomatic complexity crosses the configured threshold (default is 20
).
Examples of incorrect code for a maximum of 2:
/*eslint complexity: ["error", 2]*/
function a(x) {
if (true) {
return x;
} else if (false) {
return x+1;
} else {
return 4; // 3rd path
}
}
Examples of correct code for a maximum of 2:
/*eslint complexity: ["error", 2]*/
function a(x) {
if (true) {
return x;
} else {
return 4;
}
}
Options
Optionally, you may specify a max
object property:
"complexity": ["error", 2]
is equivalent to
"complexity": ["error", { "max": 2 }]
Deprecated: the object property maximum
is deprecated. Please use the property max
instead.
When Not To Use It
If you can't determine an appropriate complexity limit for your code, then it's best to disable this rule.

Limit Cyclomatic Complexity (complexity)
Cyclomatic complexity measures the number of linearly independent paths through a program's source code. This rule allows setting a cyclomatic complexity threshold.
function a(x) {
if (true) {
return x; // 1st path
} else if (false) {
return x+1; // 2nd path
} else {
return 4; // 3rd path
}
}
Rule Details
This rule is aimed at reducing code complexity by capping the amount of cyclomatic complexity allowed in a program. As such, it will warn when the cyclomatic complexity crosses the configured threshold (default is 20
).
Examples of incorrect code for a maximum of 2:
/*eslint complexity: ["error", 2]*/
function a(x) {
if (true) {
return x;
} else if (false) {
return x+1;
} else {
return 4; // 3rd path
}
}
Examples of correct code for a maximum of 2:
/*eslint complexity: ["error", 2]*/
function a(x) {
if (true) {
return x;
} else {
return 4;
}
}
Options
Optionally, you may specify a max
object property:
"complexity": ["error", 2]
is equivalent to
"complexity": ["error", { "max": 2 }]
Deprecated: the object property maximum
is deprecated. Please use the property max
instead.
When Not To Use It
If you can't determine an appropriate complexity limit for your code, then it's best to disable this rule.

Disallow Use of Alert (no-alert)
JavaScript's alert
, confirm

functions are widely considered to be obtrusive as UI elements and should be replaced by a more appropriate custom UI implementation. Furthermore, alert
is often used while debugging code, which should be removed before deployment to production.

Rule Details
This rule is aimed at catching debugging code that should be removed and popup UI elements that should be replaced with less obtrusive, custom UIs. As such, it will warn when it encounters alert
, prompt
, and confirm
function calls which are not shadowed.
Examples of incorrect code for this rule:
/*eslint no-alert: "error"*/
alert("here!");
confirm("Are you sure?");
prompt("What's your name?", "John Doe");
Examples of correct code for this rule:
/*eslint no-alert: "error"*/

Disallow unnecessary .call()
and .apply()
. (no-useless-call)
The function invocation can be written by Function.prototype.call()
and Function.prototype.apply()
.
But Function.prototype.call()
and Function.prototype.apply()
are slower than the normal function invocation.
Rule Details
This rule is aimed to flag usage of Function.prototype.call()
and Function.prototype.apply()
that can be replaced with the normal function invocation.
Examples of incorrect code for this rule:
/*eslint no-useless-call: "error"*/
// These are same as `foo(1, 2, 3);`
foo.call(undefined, 1, 2, 3);
foo.apply(undefined, [1, 2, 3]);
foo.call(null, 1, 2, 3);
foo.apply(null, [1, 2, 3]);
// These are same as `obj.foo(1, 2, 3);`
obj.foo.call(obj, 1, 2, 3);
obj.foo.apply(obj, [1, 2, 3]);
Examples of correct code for this rule:
/*eslint no-useless-call: "error"*/
// The `this` binding is different.
foo.call(obj, 1, 2, 3);
foo.apply(obj, [1, 2, 3]);
obj.foo.call(null, 1, 2, 3);
obj.foo.apply(null, [1, 2, 3]);
obj.foo.call(otherObj, 1, 2, 3);
obj.foo.apply(otherObj, [1, 2, 3]);
// The argument list is variadic.
foo.apply(undefined, args);
foo.apply(null, args);
obj.foo.apply(obj, args);
Known Limitations
This rule compares code statically to check whether or not thisArg
is changed.
So if the code about thisArg
is a dynamic expression, this rule cannot judge correctly.
Examples of incorrect code for this rule:
/*eslint no-useless-call: "error"*/
a[i++].foo.call(a[i++], 1, 2, 3);
Examples of correct code for this rule:
/*eslint no-useless-call: "error"*/
a[++i].foo.call(a[i], 1, 2, 3);
When Not To Use It
If you don't want to be notified about unnecessary .call()
and .apply()
, you can safely disable this rule.

Require === and !== (eqeqeq)
It is considered good practice to use the type-safe equality operators ===
and !==
instead of their regular counterparts ==
and !=
.
The reason for this is that ==
and !=
do type coercion which follows the rather obscure Abstract Equality Comparison Algorithm.
For instance, the following statements are all considered true
:
[] == false
[] == ![]
3 == "03"
If one of those occurs in an innocent-looking statement such as a == b
the actual problem is very difficult to spot.
Rule Details
This rule is aimed at eliminating the type-unsafe equality operators.
Examples of incorrect code for this rule:
/*eslint eqeqeq: "error"*/
if (x == 42) { }
if ("" == text) { }
if (obj.getStuff() != undefined) { }
The --fix
option on the command line automatically fixes some problems reported by this rule. A problem is only fixed if one of the operands is a typeof
expression, or if both operands are literals with the same type.
Options
always
The "always"
option (default) enforces the use of ===
and !==
in every situation (except when you opt-in to more specific handling of null
[see below]).
Examples of incorrect code for the "always"
option:
/*eslint eqeqeq: ["error", "always"]*/
a == b

typeof foo == 'undefined'
'hello' != 'world'
0 == 0

Examples of correct code for the "always"

bananas !== 1
value === undefined

0 === 0

This rule optionally takes a second argument, which should be an object with the following supported properties:

(default) - Always use === or !==. -
never
- Never use === or !== withnull
. -

- Do not apply this rule tonull
.
-
smart
The "smart"
option enforces the use of ===
and !==
except for these cases:
- Comparing two literal values
- Evaluating the value of
typeof
- Comparing against
null
Examples of incorrect code for the "smart"
option:

Require === and !== (eqeqeq)
It is considered good practice to use the type-safe equality operators ===
and !==
instead of their regular counterparts ==
and !=
.
The reason for this is that ==
and !=
do type coercion which follows the rather obscure Abstract Equality Comparison Algorithm.
For instance, the following statements are all considered true
:
[] == false
[] == ![]
3 == "03"
If one of those occurs in an innocent-looking statement such as a == b
the actual problem is very difficult to spot.
Rule Details
This rule is aimed at eliminating the type-unsafe equality operators.
Examples of incorrect code for this rule:
/*eslint eqeqeq: "error"*/
if (x == 42) { }
if ("" == text) { }
if (obj.getStuff() != undefined) { }
The --fix
option on the command line automatically fixes some problems reported by this rule. A problem is only fixed if one of the operands is a typeof
expression, or if both operands are literals with the same type.
Options
always
The "always"
option (default) enforces the use of ===
and !==
in every situation (except when you opt-in to more specific handling of null
[see below]).
Examples of incorrect code for the "always"
option:
/*eslint eqeqeq: ["error", "always"]*/
a == b
foo == true
bananas != 1
value == undefined
typeof foo == 'undefined'
'hello' != 'world'
0 == 0

-
smart
The "smart"
option enforces the use of ===
and !==
except for these cases:
- Comparing two literal values
- Evaluating the value of
typeof
- Comparing against
null
Examples of incorrect code for the "smart"
option:

Disallow Use of Alert (no-alert)
JavaScript's alert
, confirm
, and prompt
functions are widely considered to be obtrusive as UI elements and should be replaced by a more appropriate custom UI implementation. Furthermore, alert
is often used while debugging code, which should be removed before deployment to production.
alert("here!");
Rule Details
This rule is aimed at catching debugging code that should be removed and popup UI elements that should be replaced with less obtrusive, custom UIs. As such, it will warn when it encounters alert
, prompt
, and confirm
function calls which are not shadowed.
Examples of incorrect code for this rule:
/*eslint no-alert: "error"*/
alert("here!");
confirm("Are you sure?");
prompt("What's your name?", "John Doe");
Examples of correct code for this rule:

- Exclude checks
disallow empty block statements (no-empty)
Empty block statements, while not technically errors, usually occur due to refactoring that wasn't completed. They can cause confusion when reading code.
Rule Details
This rule disallows empty block statements. This rule ignores block statements which contain a comment (for example, in an empty catch
or finally
block of a try
statement to indicate that execution should continue regardless of errors).
Examples of incorrect code for this rule:
/*eslint no-empty: "error"*/
if (foo) {
}
while (foo) {
}
switch(foo) {
}
try {
doSomething();
} catch(ex) {
} finally {

Examples of correct code for this rule:
/*eslint no-empty: "error"*/
if (foo) {
// empty
}
while (foo) {
/* empty */
}
try {
doSomething();
} catch (ex) {
// continue regardless of error
}
try {
doSomething();
} finally {
/* continue regardless of error */
}
Options
This rule has an object option for exceptions:
-
"allowEmptyCatch": true
allows emptycatch
clauses (that is, which do not contain a comment)
allowEmptyCatch
Examples of additional correct code for this rule with the { "allowEmptyCatch": true }
option:
/* eslint no-empty: ["error", { "allowEmptyCatch": true }] */
try {
doSomething();
} catch (ex) {}
try {
doSomething();
}
catch (ex) {}
finally {
/* continue regardless of error */
}
When Not To Use It
If you intentionally use empty block statements then you can disable this rule.

disallow empty block statements (no-empty)
Empty block statements, while not technically errors, usually occur due to refactoring that wasn't completed. They can cause confusion when reading code.
Rule Details
This rule disallows empty block statements. This rule ignores block statements which contain a comment (for example, in an empty catch
or finally
block of a try
statement to indicate that execution should continue regardless of errors).
Examples of incorrect code for this rule:
/*eslint no-empty: "error"*/
if (foo) {
}
while (foo) {
}
switch(foo) {
}
try {
doSomething();
} catch(ex) {
} finally {
}
Examples of correct code for this rule:
/*eslint no-empty: "error"*/
if (foo) {
// empty
}
while (foo) {
/* empty */
}
try {
doSomething();
} catch (ex) {
// continue regardless of error
}
try {
doSomething();
} finally {
/* continue regardless of error */
}
Options
This rule has an object option for exceptions:
-
"allowEmptyCatch": true
allows emptycatch
clauses (that is, which do not contain a comment)
allowEmptyCatch
Examples of additional correct code for this rule with the { "allowEmptyCatch": true }
option:
/* eslint no-empty: ["error", { "allowEmptyCatch": true }] */
try {
doSomething();
} catch (ex) {}
try {
doSomething();
}
catch (ex) {}
finally {
/* continue regardless of error */
}
When Not To Use It
If you intentionally use empty block statements then you can disable this rule.

Require === and !== (eqeqeq)
It is considered good practice to use the type-safe equality operators ===
and !==
instead of their regular counterparts ==
and !=
.
The reason for this is that ==
and !=
do type coercion which follows the rather obscure Abstract Equality Comparison Algorithm.
For instance, the following statements are all considered true
:
[] == false
[] == ![]
3 == "03"
If one of those occurs in an innocent-looking statement such as a == b
the actual problem is very difficult to spot.
Rule Details
This rule is aimed at eliminating the type-unsafe equality operators.
Examples of incorrect code for this rule:
/*eslint eqeqeq: "error"*/
if (x == 42) { }
if ("" == text) { }
if (obj.getStuff() != undefined) { }
The --fix
option on the command line automatically fixes some problems reported by this rule. A problem is only fixed if one of the operands is a typeof
expression, or if both operands are literals with the same type.
Options
always
The "always"
option (default) enforces the use of ===
and !==
in every situation (except when you opt-in to more specific handling of null
[see below]).
Examples of incorrect code for the "always"
option:
/*eslint eqeqeq: ["error", "always"]*/
a == b
foo == true
bananas != 1
value == undefined
typeof foo == 'undefined'
'hello' != 'world'
0 == 0
true == true

Examples of correct code for the "always"
option:

a === b
foo === true
bananas !== 1
value === undefined
typeof foo === 'undefined'
'hello' !== 'world'
0 === 0
true === true
foo === null
This rule optionally takes a second argument, which should be an object with the following supported properties:
-
"null"
: Customize how this rule treatsnull
literals. Possible values:-
always
(default) - Always use === or !==. -
never
- Never use === or !== withnull
. -
ignore
- Do not apply this rule tonull
.
-
smart
The "smart"
option enforces the use of ===
and !==
except for these cases:
- Comparing two literal values
- Evaluating the value of
typeof
- Comparing against
null
Examples of incorrect code for the "smart"
option:
/*eslint eqeqeq: ["error", "smart"]*/
// comparing two variables requires ===
a == b
// only one side is a literal
foo == true
bananas != 1
// comparing to undefined requires ===
value == undefined
Examples of correct code for the "smart"
option:
/*eslint eqeqeq: ["error", "smart"]*/
typeof foo == 'undefined'
'hello' != 'world'
0 == 0
true == true
foo == null
allow-null
Deprecated: Instead of using this option use "always" and pass a "null" option property with value "ignore". This will tell eslint to always enforce strict equality except when comparing with the null
literal.

Disallow unnecessary .call()
and .apply()
. (no-useless-call)
The function invocation can be written by Function.prototype.call()
and Function.prototype.apply()
.
But Function.prototype.call()
and Function.prototype.apply()
are slower than the normal function invocation.
Rule Details
This rule is aimed to flag usage of Function.prototype.call()
and Function.prototype.apply()
that can be replaced with the normal function invocation.
Examples of incorrect code for this rule:
/*eslint no-useless-call: "error"*/
// These are same as `foo(1, 2, 3);`
foo.call(undefined, 1, 2, 3);
foo.apply(undefined, [1, 2, 3]);
foo.call(null, 1, 2, 3);
foo.apply(null, [1, 2, 3]);
// These are same as `obj.foo(1, 2, 3);`
obj.foo.call(obj, 1, 2, 3);
obj.foo.apply(obj, [1, 2, 3]);
Examples of correct code for this rule:
/*eslint no-useless-call: "error"*/
// The `this` binding is different.
foo.call(obj, 1, 2, 3);
foo.apply(obj, [1, 2, 3]);
obj.foo.call(null, 1, 2, 3);
obj.foo.apply(null, [1, 2, 3]);
obj.foo.call(otherObj, 1, 2, 3);
obj.foo.apply(otherObj, [1, 2, 3]);
// The argument list is variadic.
foo.apply(undefined, args);
foo.apply(null, args);
obj.foo.apply(obj, args);
Known Limitations
This rule compares code statically to check whether or not thisArg
is changed.
So if the code about thisArg
is a dynamic expression, this rule cannot judge correctly.
Examples of incorrect code for this rule:
/*eslint no-useless-call: "error"*/
a[i++].foo.call(a[i++], 1, 2, 3);
Examples of correct code for this rule:
/*eslint no-useless-call: "error"*/
a[++i].foo.call(a[i], 1, 2, 3);
When Not To Use It
If you don't want to be notified about unnecessary .call()
and .apply()
, you can safely disable this rule.

- Read upRead up
- Exclude checks
Require Guarding for-in (guard-for-in)
Looping over objects with a for in
loop will include properties that are inherited through the prototype chain. This behavior can lead to unexpected items in your for loop.
for (key in foo) {
doSomething(key);
}
Note that simply checking foo.hasOwnProperty(key)
is likely to cause an error in some cases; see [no-prototype-builtins](no-prototype-builtins.md).
Rule Details
This rule is aimed at preventing unexpected behavior that could arise from using a for in
loop without filtering the results in the loop. As such, it will warn when for in
loops do not filter their results with an if
statement.
Examples of incorrect code for this rule:
/*eslint guard-for-in: "error"*/
for (key in foo) {
doSomething(key);
}
Examples of correct code for this rule:
/*eslint guard-for-in: "error"*/
for (key in foo) {
if (Object.prototype.hasOwnProperty.call(foo, key)) {
doSomething(key);
}
if ({}.hasOwnProperty.call(foo, key)) {

Require IIFEs to be Wrapped (wrap-iife)
You can immediately invoke function expressions, but not function declarations. A common technique to create an immediately-invoked function expression (IIFE) is to wrap a function declaration in parentheses. The opening parentheses causes the contained function to be parsed as an expression, rather than a declaration.
// function expression could be unwrapped
var x = function () { return { y: 1 };}();
// function declaration must be wrapped
function () { /* side effects */ }(); // SyntaxError
Rule Details
This rule requires all immediately-invoked function expressions to be wrapped in parentheses.
Options
This rule has two options, a string option and an object option.
String option:
-
"outside"
enforces always wrapping the call expression. The default is"outside"
. -

"functionPrototypeMethods": true
additionally enforces wrapping function expressions invoked using.call
and.apply
. The default isfalse
.

Duplicated Code
Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:
Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.
When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).
Tuning
This issue has a mass of 346.
We set useful threshold defaults for the languages we support but you may want to adjust these settings based on your project guidelines.
The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.
If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.

The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.
If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.

Duplicated Code
Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:
Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.
When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).

Duplicated Code
Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:
Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.
When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).
Tuning
This issue has a mass of 66.
We set useful threshold defaults for the languages we support but you may want to adjust these settings based on your project guidelines.
The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.
If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.
