描述

In the subsection `Array Methods`:

> With the exception of `forEach`, the above functions do not modify the array they are given.

`forEach` behaves _exactly_ in the same manner as the rest of those functions. None of them, `forEach` included, modifies the original array.

(But also none of them can prevent that _you_ change it inside the iterating function)
