jquery ajax tutorial (6)
So, Ajax is a technology paradigm, whereas jquery is a library so can't compare them.
Actually only one of them is a programming language.
To sum up:
- jQuery is for simplifing common tasks with AJAX and page manipulation (style, animation, etc.)
Finally, an example just to see some syntax:
JS is a client-side programming language.
jQuery is a framework, but isn't the only one. Another JS frameworks are AngularJS, Mootools, NodeJS, BackboneJS, etcetera. With anyone of this frameworks you will do any action that pure JS can't do, or any "complex" (I don't find the correct word) action. As Void said, adapting his answer to my answer about frameworks: "makes life easier for people who want to program for the browser."
With AJAX you can communicate your Web page to the server. AJAX depends on JS to work.
