    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"

    Unary operator '++' used.
    Invalid

          for (let i = 0; i < keys.length; i++) {
    Severity: Minor
    Found in src/components/graph/TableChart.js by eslint

    disallow the unary operators ++ and -- (no-plusplus)

    Because the unary ++ and -- operators are subject to automatic semicolon insertion, differences in whitespace can change semantics of source code.

    var i = 10;
var j = 20;

i ++
j
// i = 11, j = 20
    var i = 10;
var j = 20;

i
++
j
// i = 10, j = 21

    Rule Details

    This rule disallows the unary operators ++ and --.

    Examples of incorrect code for this rule:

    /*eslint no-plusplus: "error"*/

var foo = 0;
foo++;

var bar = 42;
bar--;

for (i = 0; i < l; i++) {
    return;
}

    Examples of correct code for this rule:

    /*eslint no-plusplus: "error"*/

var foo = 0;
foo += 1;

var bar = 42;
bar -= 1;

for (i = 0; i < l; i += 1) {
    return;
}

    Options

    This rule has an object option.

    • "allowForLoopAfterthoughts": true allows unary operators ++ and -- in the afterthought (final expression) of a for loop.
