From the mentioned methods to access external resources from other domains. Where does REST APIs fit in?

Hi David,

REST is just one type of API.

When you connect to an API, you are essentially just giving instructions to code running on a server somewhere. When you execute:

$.ajax({
  url: "exampleSite/news",
  context: document.body
}).done(function() {
  $( this ).addClass( "done" );
});

The code running on a server somewhere might do something like this:

Function that runs whenever user connects to /news

GET request

Any query parameters? Nope, so we will search for all news stories and use the default of 10 stories to return, with the latest stories being the ones the client wants

Hey database, it is the server, can I have the latest 10 stories in the news database?

Sure server, here is the data that you wanted.

Sending the news data as the response to the AJAX request

After that, the browser will receive the data, and the even loop will call the AJAX call's done callable.
