JavaScript Understanding "this" in JavaScript

Methods Explained: .apply .bind .call

The other way is within functions that are invoked using the .call, .apply, or bind methods. We'll explore these in another workshop.

Is there a workshop/tutorial out there that adequately explains the uses of these methods in relation to the 'this' keyword.

Please help!

-Thanks

According to the Treehouse JavaScript Content Roadmap on Trello, there's a planned workshop for 'JavaScripts call, apply, and bind Methods'. That was added in May 2015 though...

@hstn, any updates on that Workshop?

That link you provided didn't jump to the right place, just adding another link that hopefully works: https://github.com/getify/You-Dont-Know-JS

Thanks for the resource!

As Maxwell mentioned, MDN's JavaScript reference is a good resource. Here was a reference to "this" from MDN (scroll down the article to find explanations for "call", "apply", and "bind"): https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/this
