What JavaScript libraries are known to use the global dollar sign: window.$?

Question

Which JavaScript libraries take over the $ variable in the global scope?

If the library provides a different name on the global namespace, or provides a method to relinquish window.$, could you link to the proper function in their documentation any maybe a little code example of its use?

Having such a list could be useful in debugging potential conflicts with each other very quickly.

Answer 1

Scanning this page, the only ones that come to mind are:

• jQuery - Provides jQuery.noConflict() to release the $
• Prototype
• MooTools

Answer 2

Also zepto: http://zeptojs.com/

zepto actually matches most of the jQuery API.
