Passing scope to forEach

Question

I\'m trying to use a callback method addToCount instead of anonymous function in forEach. But I can\'t access this.count in it (return

Answer 1

You need to use Function#bind to bind a scope:

words.forEach(this.addToCount.bind(this));

Note that this is not available in all browsers: you should use a shim (as provided in the link above) to add it in the browsers that don't support Function#bind.

As dandavis points out in the comments, you can pass a value to Array#forEach as the context for the callback:

words.forEach(this.addToCount, this);
