unicorn/prefer-prototype-methods Pedantic
What it does
This rule prefers borrowing methods from the prototype instead of the instance.
Why is this bad?
“Borrowing” a method from an instance of Array or Object is less clear than getting it from the corresponding prototype.
Examples
Examples of incorrect code for this rule:
javascript
const array = [].slice.apply(bar);
const type = {}.toString.call(foo);
Reflect.apply([].forEach, arrayLike, [callback]);Examples of correct code for this rule:
javascript
const array = Array.prototype.slice.apply(bar);
const type = Object.prototype.toString.call(foo);
Reflect.apply(Array.prototype.forEach, arrayLike, [callback]);
const maxValue = Math.max.apply(Math, numbers);
