Cognitive Complexity
Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.
A method's cognitive complexity is based on a few simple rules:
- Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
- Code is considered more complex for each "break in the linear flow of the code"
- Code is considered more complex when "flow breaking structures are nested"

Disallow Unused Variables (no-unused-vars)
Variables that are declared and not used anywhere in the code are most likely an error due to incomplete refactoring. Such variables take up space in the code and can lead to confusion by readers.
Rule Details
This rule is aimed at eliminating unused variables, functions, and function parameters.
A variable foo
is considered to be used if any of the following are true:
- It is called (
foo()
) or constructed (new foo()
) - It is read (
var bar = foo
) - It is passed into a function as an argument (
doSomething(foo)
) - It is read inside of a function that is passed to another function (
doSomething(function() { foo(); })
)
A variable is not considered to be used if it is only ever declared (var foo = 5
) or assigned to (foo = 7
).
Examples of incorrect code for this rule:
/*eslint no-unused-vars: "error"*/
/*global some_unused_var*/
// It checks variables you have defined as global
some_unused_var = 42;
var x;
// Write-only variables are not considered as used.
var y = 10;
y = 5;
// A read for a modification of itself is not considered as used.
var z = 0;
z = z + 1;
// By default, unused arguments cause warnings.
(function(foo) {
return 5;
})();
// Unused recursive functions also cause warnings.
function fact(n) {
if (n < 2) return 1;
return n * fact(n - 1);
}
// When a function definition destructures an array, unused entries from the array also cause warnings.
function getY([x, y]) {
return y;
}
Examples of correct code for this rule:
/*eslint no-unused-vars: "error"*/
var x = 10;
alert(x);
// foo is considered used here
myFunc(function foo() {
// ...
}.bind(this));
(function(foo) {
return foo;
})();
var myFunc;
myFunc = setTimeout(function() {
// myFunc is considered used
myFunc();
}, 50);
// Only the second argument from the descructured array is used.
function getY([, y]) {
return y;
}
exported
In environments outside of CommonJS or ECMAScript modules, you may use var
to create a global variable that may be used by other scripts. You can use the /* exported variableName */
comment block to indicate that this variable is being exported and therefore should not be considered unused.
Note that /* exported */
has no effect for any of the following:
- when the environment is
node
orcommonjs
- when
parserOptions.sourceType
ismodule
- when
ecmaFeatures.globalReturn
istrue
The line comment // exported variableName
will not work as exported
is not line-specific.
Examples of correct code for /* exported variableName */
operation:
/* exported global_var */
var global_var = 42;
Options
This rule takes one argument which can be a string or an object. The string settings are the same as those of the vars
property (explained below).
By default this rule is enabled with all
option for variables and after-used
for arguments.
{
"rules": {
"no-unused-vars": ["error", { "vars": "all", "args": "after-used", "ignoreRestSiblings": false }]
}
}
vars
The vars
option has two settings:
-
all
checks all variables for usage, including those in the global scope. This is the default setting. -
local
checks only that locally-declared variables are used but will allow global variables to be unused.
vars: local
Examples of correct code for the { "vars": "local" }
option:
/*eslint no-unused-vars: ["error", { "vars": "local" }]*/
/*global some_unused_var */
some_unused_var = 42;
varsIgnorePattern
The varsIgnorePattern
option specifies exceptions not to check for usage: variables whose names match a regexp pattern. For example, variables whose names contain ignored
or Ignored
.
Examples of correct code for the { "varsIgnorePattern": "[iI]gnored" }
option:
/*eslint no-unused-vars: ["error", { "varsIgnorePattern": "[iI]gnored" }]*/
var firstVarIgnored = 1;
var secondVar = 2;
console.log(secondVar);
args
The args
option has three settings:
-
after-used
- unused positional arguments that occur before the last used argument will not be checked, but all named arguments and all positional arguments after the last used argument will be checked. -
all
- all named arguments must be used. -
none
- do not check arguments.
args: after-used
Examples of incorrect code for the default { "args": "after-used" }
option:
/*eslint no-unused-vars: ["error", { "args": "after-used" }]*/
// 2 errors, for the parameters after the last used parameter (bar)
// "baz" is defined but never used
// "qux" is defined but never used
(function(foo, bar, baz, qux) {
return bar;
})();
Examples of correct code for the default { "args": "after-used" }
option:
/*eslint no-unused-vars: ["error", {"args": "after-used"}]*/
(function(foo, bar, baz, qux) {
return qux;
})();
args: all
Examples of incorrect code for the { "args": "all" }
option:
/*eslint no-unused-vars: ["error", { "args": "all" }]*/
// 2 errors
// "foo" is defined but never used
// "baz" is defined but never used
(function(foo, bar, baz) {
return bar;
})();
args: none
Examples of correct code for the { "args": "none" }
option:
/*eslint no-unused-vars: ["error", { "args": "none" }]*/
(function(foo, bar, baz) {
return bar;
})();
ignoreRestSiblings
The ignoreRestSiblings
option is a boolean (default: false
). Using a Rest Property it is possible to "omit" properties from an object, but by default the sibling properties are marked as "unused". With this option enabled the rest property's siblings are ignored.
Examples of correct code for the { "ignoreRestSiblings": true }
option:
/*eslint no-unused-vars: ["error", { "ignoreRestSiblings": true }]*/
// 'type' is ignored because it has a rest property sibling.
var { type, ...coords } = data;
argsIgnorePattern
The argsIgnorePattern
option specifies exceptions not to check for usage: arguments whose names match a regexp pattern. For example, variables whose names begin with an underscore.
Examples of correct code for the { "argsIgnorePattern": "^_" }
option:
/*eslint no-unused-vars: ["error", { "argsIgnorePattern": "^_" }]*/
function foo(x, _y) {
return x + 1;
}
foo();
caughtErrors
The caughtErrors
option is used for catch
block arguments validation.
It has two settings:
-
none
- do not check error objects. This is the default setting. -
all
- all named arguments must be used.
caughtErrors: none
Not specifying this rule is equivalent of assigning it to none
.
Examples of correct code for the { "caughtErrors": "none" }
option:
/*eslint no-unused-vars: ["error", { "caughtErrors": "none" }]*/
try {
//...
} catch (err) {
console.error("errors");
}
caughtErrors: all
Examples of incorrect code for the { "caughtErrors": "all" }
option:
/*eslint no-unused-vars: ["error", { "caughtErrors": "all" }]*/
// 1 error
// "err" is defined but never used
try {
//...
} catch (err) {
console.error("errors");
}
caughtErrorsIgnorePattern
The caughtErrorsIgnorePattern
option specifies exceptions not to check for usage: catch arguments whose names match a regexp pattern. For example, variables whose names begin with a string 'ignore'.
Examples of correct code for the { "caughtErrorsIgnorePattern": "^ignore" }
option:
/*eslint no-unused-vars: ["error", { "caughtErrorsIgnorePattern": "^ignore" }]*/
try {
//...
} catch (ignoreErr) {
console.error("errors");
}
When Not To Use It
If you don't want to be notified about unused variables or function arguments, you can safely turn this rule off. Source: http://eslint.org/docs/rules/
Headers should be surrounded by blank lines Open
## Add a form
- Read upRead up
- Exclude checks
MD022 - Headers should be surrounded by blank lines
Tags: headers, blank_lines
Aliases: blanks-around-headers
This rule is triggered when headers (any style) are either not preceded or not followed by a blank line:
# Header 1
Some text
Some more text
## Header 2
To fix this, ensure that all headers have a blank line both before and after (except where the header is at the beginning or end of the document):
# Header 1
Some text
Some more text
## Header 2
Rationale: Aside from aesthetic reasons, some parsers, including kramdown, will not parse headers that don't have a blank line before, and will parse them as regular text.

MD009 - Trailing spaces
Tags: whitespace
Aliases: no-trailing-spaces
Parameters: br_spaces (number; default: 0)
This rule is triggered on any lines that end with whitespace. To fix this, find the line that is triggered and remove any trailing spaces from the end.
The brspaces parameter allows an exception to this rule for a specific amount of trailing spaces used to insert an explicit line break/br element. For example, set brspaces to 2 to allow exactly 2 spaces at the end of a line.
Note: you have to set brspaces to 2 or higher for this exception to take effect - you can't insert a br element with just a single trailing space, so if you set brspaces to 1, the exception will be disabled, just as if it was set to the default of 0.

enforce the consistent use of either backticks, double, or single quotes (quotes)
JavaScript allows you to define strings in one of three ways: double quotes, single quotes, and backticks (as of ECMAScript 6). For example:
/*eslint-env es6*/
var double = "double";
var single = 'single';
var backtick = `backtick`; // ES6 only
Each of these lines creates a string and, in some cases, can be used interchangeably. The choice of how to define strings in a codebase is a stylistic one outside of template literals (which allow embedded of expressions to be interpreted).
Many codebases require strings to be defined in a consistent manner.
Rule Details
This rule enforces the consistent use of either backticks, double, or single quotes.
Options
This rule has two options, a string option and an object option.
String option:
-
"double"
(default) requires the use of double quotes wherever possible -
"single"
requires the use of single quotes wherever possible -
"backtick"
requires the use of backticks wherever possible
Object option:
-
"avoidEscape": true
allows strings to use single-quotes or double-quotes so long as the string contains a quote that would have to be escaped otherwise -
"allowTemplateLiterals": true
allows strings to use backticks
Deprecated: The object property avoid-escape
is deprecated; please use the object property avoidEscape
instead.
double
Examples of incorrect code for this rule with the default "double"
option:
/*eslint quotes: ["error", "double"]*/
var single = 'single';
var unescaped = 'a string containing "double" quotes';
var backtick = `back\ntick`; // you can use \n in single or double quoted strings
Examples of correct code for this rule with the default "double"
option:
/*eslint quotes: ["error", "double"]*/
/*eslint-env es6*/
var double = "double";
var backtick = `back
tick`; // backticks are allowed due to newline
var backtick = tag`backtick`; // backticks are allowed due to tag
single
Examples of incorrect code for this rule with the "single"
option:
/*eslint quotes: ["error", "single"]*/
var double = "double";
var unescaped = "a string containing 'single' quotes";
Examples of correct code for this rule with the "single"
option:
/*eslint quotes: ["error", "single"]*/
/*eslint-env es6*/
var single = 'single';
var backtick = `back${x}tick`; // backticks are allowed due to substitution
backticks
Examples of incorrect code for this rule with the "backtick"
option:
/*eslint quotes: ["error", "backtick"]*/
var single = 'single';
var double = "double";
var unescaped = 'a string containing `backticks`';
Examples of correct code for this rule with the "backtick"
option:
/*eslint quotes: ["error", "backtick"]*/
/*eslint-env es6*/
var backtick = `backtick`;
avoidEscape
Examples of additional correct code for this rule with the "double", { "avoidEscape": true }
options:
/*eslint quotes: ["error", "double", { "avoidEscape": true }]*/
var single = 'a string containing "double" quotes';
Examples of additional correct code for this rule with the "single", { "avoidEscape": true }
options:
/*eslint quotes: ["error", "single", { "avoidEscape": true }]*/
var double = "a string containing 'single' quotes";
Examples of additional correct code for this rule with the "backtick", { "avoidEscape": true }
options:
/*eslint quotes: ["error", "backtick", { "avoidEscape": true }]*/
var double = "a string containing `backtick` quotes"
allowTemplateLiterals
Examples of additional correct code for this rule with the "double", { "allowTemplateLiterals": true }
options:
/*eslint quotes: ["error", "double", { "allowTemplateLiterals": true }]*/
var double = "double";
var double = `double`;
Examples of additional correct code for this rule with the "single", { "allowTemplateLiterals": true }
options:
/*eslint quotes: ["error", "single", { "allowTemplateLiterals": true }]*/
var single = 'single';
var single = `single`;
{ "allowTemplateLiterals": false }
will not disallow the usage of all template literals. If you want to forbid any instance of template literals, use no-restricted-syntax and target the TemplateLiteral
selector.
When Not To Use It
If you do not need consistency in your string styles, you can safely disable this rule. Source: http://eslint.org/docs/rules/
