Description

Description

Add a minimumItems option so only arrays from a certain known size will be linted (default 0).

The rule can sometimes be too strict, using sets over arrays is usually more performant the more elements it has, and it's negligible in small numbers and readability is preferred.

Fail

minimumItems: 5

const array = [1, 2, 3, 4, 5, 6, 7];
const hasValue = value => array.includes(value);

Pass

minimumItems: 5

const array = [1, 2];
const hasValue = value => array.includes(value);
