Confusion: Ajax Framework vs JavaScript Framework?

I was under the impression that jQuery is JavaScript Framework, but when am searching开发者_如何学编程 for AJAX Framework it appears that jQuery is also being suggested as best AJAX Framework.

Reference: Best Ajax Framework

My Question:

1. What is Ajax Framework and how it is different from JavaScript Framework like jQuery ?
2. What are best known Ajax Framework ?
3. What are best known JavaScript Framework ?

AJAX is a way to asynchronously communicate with a server using Javascript. jQuery provides functions to help you do AJAX things, so it's an AJAX framework, but it also provides other Javascript tools, so it's a general Javascript framework too.

"Best" rather depends on what you want the framework to do; I happen to like jQuery for both

Understand the terms and the relationships:

• AJAX (Async. JavaScript and XML) uses JavaScript
• JavaScript is a scripting language
• Therefore, AJAX is a feature of Web JavaScript
• jQuery is a JavaScript framework
• Therefore, jQuery can include AJAX features

About the best AJAX and JS frameworks... I tried jQuery and I was satisfied.

Ajax (Asynchronous Javascript And XML) is just what it sounds like: a javascript technique for asynchronous communication (that is, you don't have to reload the page).

Of course, you can use javascript without ajax, but "ajax without javascript" is meaningless.

My personal favorite framework for both is jQuery.

Indeed, one of my biggest pet peeves is when people are like "oh, yeah, there's no Flash on this site, it's all AJAX" in reference to the animation used. AJAX was initially coined to refer to the technique of using javascript to asynchronously load XML (or sometimes json) data from a server via an XMLHttpRequest. Many Javascript frameworks (jQuery, prototype, mootools) have implementations of AJAX methodologies wrapped in them, but to call these frameworks an "AJAX framework" is misleading as they do much more. But AJAX has become a defacto buzzword over the years so:

1) there's really no difference
2+3) jQuery, prototype, mootools are the big three. jQuery is the most popular (and in my humble opinion, easily the best)
