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"

- Exclude checks
Disallow or enforce spaces inside of blocks after opening block and before closing block (block-spacing)
Rule Details
This rule enforces consistent spacing inside an open block token and the next token on the same line. This rule also enforces consistent spacing inside a close block token and previous token on the same line.
Options
This rule has a string option:
-
"always"(default) requires one or more spaces -
"never"disallows spaces
always
Examples of incorrect code for this rule with the default "always" option:
/*eslint block-spacing: "error"*/
function foo() {return true;}
if (foo) { bar = 0;}
function baz() {let i = 0;
return i;
}Examples of correct code for this rule with the default "always" option:
/*eslint block-spacing: "error"*/
function foo() { return true; }
if (foo) { bar = 0; }never
Examples of incorrect code for this rule with the "never" option:
/*eslint block-spacing: ["error", "never"]*/
function foo() { return true; }
if (foo) { bar = 0;}Examples of correct code for this rule with the "never" option:
/*eslint block-spacing: ["error", "never"]*/
function foo() {return true;}
if (foo) {bar = 0;}When Not To Use It
If you don't want to be notified about spacing style inside of blocks, you can safely disable this rule. Source: http://eslint.org/docs/rules/
