disallow unnecessary semicolons (no-extra-semi)
Typing mistakes and misunderstandings about where semicolons are required can lead to semicolons that are unnecessary. While not technically an error, extra semicolons can cause confusion when reading code.
Rule Details
This rule disallows unnecessary semicolons.
Examples of incorrect code for this rule:
/*eslint no-extra-semi: "error"*/
var x = 5;;
function foo() {
// code
};
Examples of correct code for this rule:

disallow variable redeclaration (no-redeclare)
In JavaScript, it's possible to redeclare the same variable name using var
. This can lead to confusion as to where the variable is actually declared and initialized.
Rule Details
This rule is aimed at eliminating variables that have multiple declarations in the same scope.
Examples of incorrect code for this rule:
/*eslint no-redeclare: "error"*/
var a = 3;
var a = 10;
Examples of correct code for this rule:
/*eslint no-redeclare: "error"*/
var a = 3;
// ...
a = 10;
Options
This rule takes one optional argument, an object with a boolean property "builtinGlobals"
. It defaults to false
.
If set to true
, this rule also checks redeclaration of built-in globals, such as Object
, Array
, Number
...
builtinGlobals
Examples of incorrect code for the { "builtinGlobals": true }
option:
/*eslint no-redeclare: ["error", { "builtinGlobals": true }]*/

environment:
/*eslint no-redeclare: ["error", { "builtinGlobals": true }]*/
/*eslint-env browser*/
var top = 0;
The browser
environment has many built-in global variables (for example, top
). Some of built-in global variables cannot be redeclared.

Missing radix parameter. Open
return $navigation.find(baseItemSelector + ':eq('+parseInt(obj.currentIndex()-1)+')');
- Read upRead up
- Exclude checks
Require Radix Parameter (radix)
When using the parseInt()
function it is common to omit the second argument, the radix, and let the function try to determine from the first argument what type of number it is. By default, parseInt()
will autodetect decimal and hexadecimal (via 0x
prefix). Prior to ECMAScript 5, parseInt()
also autodetected octal literals, which caused problems because many developers assumed a leading 0
would be ignored.
This confusion led to the suggestion that you always use the radix parameter to parseInt()
to eliminate unintended consequences. So instead of doing this:
var num = parseInt("071"); // 57
Do this:
var num = parseInt("071", 10); // 71
ECMAScript 5 changed the behavior of parseInt()
so that it no longer autodetects octal literals and instead treats them as decimal literals. However, the differences between hexadecimal and decimal interpretation of the first parameter causes many developers to continue using the radix parameter to ensure the string is interpreted in the intended way.
On the other hand, if the code is targeting only ES5-compliant environments passing the radix 10
may be redundant. In such a case you might want to disallow using such a radix.
Rule Details
This rule is aimed at preventing the unintended conversion of a string to a number of a different base than intended or at preventing the redundant 10
radix if targeting modern environments only.
Options
There are two options for this rule:
-
"always"
enforces providing a radix (default) -
"as-needed"
disallows providing the10
radix
always
Examples of incorrect code for the default "always"
option:
/*eslint radix: "error"*/
var num = parseInt("071");
var num = parseInt(someValue);
var num = parseInt("071", "abc");
var num = parseInt();
Examples of correct code for the default "always"
option:
/*eslint radix: "error"*/
var num = parseInt("071", 10);
var num = parseInt("071", 8);
var num = parseFloat(someValue);
as-needed
Examples of incorrect code for the "as-needed"
option:
/*eslint radix: ["error", "as-needed"]*/
var num = parseInt("071", 10);
var num = parseInt("071", "abc");
var num = parseInt();
Examples of correct code for the "as-needed"
option:
/*eslint radix: ["error", "as-needed"]*/
var num = parseInt("071");
var num = parseInt("071", 8);
var num = parseFloat(someValue);
When Not To Use It
If you don't want to enforce either presence or omission of the 10
radix value you can turn this rule off.

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"]*/

except for these cases:
- Comparing two literal values
- Evaluating the value of
typeof
- Comparing against
null

0 == 0

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"
. -
"inside"
enforces always wrapping the function expression. -
"any"
enforces always wrapping, but allows either style.
Object option:
-
"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 60.
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.
