The name of Array.prototype.includes

# Axel Rauschmayer (9 years ago)

There are two existing methods that are loosely similar to Array.prototype.includes():

String.prototype.includes()
Set.prototype.has()

Isn’t #2 more similar than #1? Shouldn’t the method be called Array.prototype.has, then?

There are two existing methods that are loosely similar to `Array.prototype.includes()`:

1. `String.prototype.includes()`
2. `Set.prototype.has()`

Isn’t #2 more similar than #1? Shouldn’t the method be called `Array.prototype.has`, then?
