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 multiple empty lines (no-multiple-empty-lines)

Some developers prefer to have multiple blank lines removed, while others feel that it helps improve readability. Whitespace is useful for separating logical sections of code, but excess whitespace takes up more of the screen.

Rule Details

This rule aims to reduce the scrolling required when reading through your code. It will warn when the maximum amount of empty lines has been exceeded.

Options

This rule has an object option:

  • "max" (default: 2) enforces a maximum number of consecutive empty lines.
  • "maxEOF" enforces a maximum number of consecutive empty lines at the end of files.
  • "maxBOF" enforces a maximum number of consecutive empty lines at the beginning of files.

max

Examples of incorrect code for this rule with the default { "max": 2 } option:

/*eslint no-multiple-empty-lines: "error"*/

var foo = 5;



var bar = 3;

Examples of correct code for this rule with the default { "max": 2 } option:

/*eslint no-multiple-empty-lines: "error"*/

var foo = 5;


var bar = 3;

maxEOF

Examples of incorrect code for this rule with the { max: 2, maxEOF: 1 } options:

/*eslint no-multiple-empty-lines: ["error", { "max": 2, "maxEOF": 1 }]*/

var foo = 5;


var bar = 3;

Examples of correct code for this rule with the { max: 2, maxEOF: 1 } options:

/*eslint no-multiple-empty-lines: ["error", { "max": 2, "maxEOF": 1 }]*/

var foo = 5;


var bar = 3;

maxBOF

Examples of incorrect code for this rule with the { max: 2, maxBOF: 1 } options:

/*eslint no-multiple-empty-lines: ["error", { "max": 2, "maxBOF": 1 }]*/


var foo = 5;


var bar = 3;

Examples of correct code for this rule with the { max: 2, maxBOF: 1 } options:

/*eslint no-multiple-empty-lines: ["error", { "max": 2, "maxBOF": 1}]*/

var foo = 5;


var bar = 3;

When Not To Use It

If you do not care about extra blank lines, turn this off. Source: http://eslint.org/docs/rules/
