Someone asked a similar question just recently. Here's what I said then:

There's an entire 13-minute workshop for Understanding "this" in JavaScript.

The short version is that it stands for the current context. Within an object method, for example, it would represent the object itself. In an event handler, it would be the element that triggered the event.

Thank you!

There's actually a Treehouse workshop on this that you may want to check out. I think of this as the context of what's calling this, though that may not help. As a general practice, while you're new, anytime you use or see this, trying declaring console.log(this).

Thank you for your support! It really helps.
