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"

Require Camelcase (camelcase)
When it comes to naming variables, style guides generally fall into one of two camps: camelcase (variableName
) and underscores (variable_name
). This rule focuses on using the camelcase approach. If your style guide calls for camelcasing your variable names, then this rule is for you!
Rule Details
This rule looks for any underscores (_
) located within the source code. It ignores leading and trailing underscores and only checks those in the middle of a variable name. If ESLint decides that the variable is a constant (all uppercase), then no warning will be thrown. Otherwise, a warning will be thrown. This rule only flags definitions and assignments but not function calls. In case of ES6 import
statements, this rule only targets the name of the variable that will be imported into the local module scope.
Options
This rule has an object option:
-
"properties": "always"
(default) enforces camelcase style for property names -
"properties": "never"
does not check property names
always
Examples of incorrect code for this rule with the default { "properties": "always" }
option:
/*eslint camelcase: "error"*/
import { no_camelcased } from "external-module"
var my_favorite_color = "#112C85";
function do_something() {
// ...
}
obj.do_something = function() {
// ...
};
var obj = {
my_pref: 1
};

var foo = bar.baz_boom;
var foo = { qux: bar.baz_boom };

option:
/*eslint camelcase: ["error", {properties: "never"}]*/
var obj = {
my_pref: 1

When Not To Use It
If you have established coding standards using a different naming convention (separating words with underscores), turn this rule off. Source: http://eslint.org/docs/rules/
