jQuery Cheatsheet from version 1.0 to 1.9
Cheatsheets are quite handy and useful. And found a website where you can find the jQuery cheatsheets from 1.0 to 1.9. And one interesting thing about these cheatsheets is that it shows what was added in new version or what was removed.
Feel free to contact me for any help related to jQuery, I will gladly help you.
