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 Guarding for-in (guard-for-in)
Looping over objects with a for in
loop will include properties that are inherited through the prototype chain. This behavior can lead to unexpected items in your for loop.
for (key in foo) {
doSomething(key);
}
Note that simply checking foo.hasOwnProperty(key)
is likely to cause an error in some cases; see [no-prototype-builtins](no-prototype-builtins.md).
Rule Details
This rule is aimed at preventing unexpected behavior that could arise from using a for in
loop without filtering the results in the loop. As such, it will warn when for in
loops do not filter their results with an if
statement.
Examples of incorrect code for this rule:
/*eslint guard-for-in: "error"*/
for (key in foo) {
doSomething(key);
}
Examples of correct code for this rule:
/*eslint guard-for-in: "error"*/
for (key in foo) {
if (Object.prototype.hasOwnProperty.call(foo, key)) {
doSomething(key);
}
if ({}.hasOwnProperty.call(foo, key)) {
doSomething(key);
}
}
