How do I get the right “this” in an Array.map?

Question

I assume there is some application of call or apply here but I\'m not sure how to implement it.

Answer 1

map allows a second argument called "thisArg" so you just use that like so:

showFooForEach: function() {
    this.things.map(function(thing) {
      console.log(this.foo, thing);
    },this);
