On: How JavaScript Works: deep dive into call, apply, ...

[wruza]

Anything that substitutes ‘this’ but doesn’t want to put a function into that object.

  const {filter} = []
  class Foo {
    less() {
      return filter.call(this, sometest)
    }
  }

There is no way to closure it somehow without (temporarily) modifying an instance of Foo. (The next obvious question is “why” and the answer is “metaprogramming”.)

[bluepnume → wruza]

I would rather re-implement `filter` in a way that is specific to `Foo`, than to attempt to use an array method on my class.
