can you use node.js with ajax?

i know that node.js can be used as backend (as ive heard) and we learn that in the track (soon after the ajax course). however the instructor always uses php as a backend language example. should i learn php or can i just continue with the track, learn node.js, and will that be good enough?

or is node.js very different from php (all i know is that both of them are 'backend languages')

Hey Sibal,

You can definitely use node.js with AJAX. AJAX is basically a way for the front-end to communicate with the back-end. While the back-end can be any server side language (PHP, Ruby, C#, node.js, etc.), the front-end is javaScript - the language of the browser. AJAX leverages the XMLhttpRequest API (which is javaScript) to transfer data between front and back (note: the data does not have to be XML and is more commonly JSON). More to the point of your question, I would recommend learning node.js, and more specifically javaScript. You don't need to know PHP to use AJAX.

Best,

Clayton

Yep, with node.js you can use javascript for both the front and back end.
