The highlight reel: Chapter 1

So you’re probably thinking, “What’s a highlight reel doing at the beginning of the chapter?

That’s not normal.” You’re right... but this is Head Rush, remember? Before you go

Asynchronous applications make requests using a

JavaScript object, and not a form submit.

Your requests and responses are handled by the web

JavaScript with the server’s response.
