jquery is the best for appling Javascript advance features

jquery is the best for appling Javascript advance features like Ajax, Fadein fadeout, Sliding meenu slideshow.

i was thinking that i must me very deficule but it is very easy to implement  just u need to know the basics of Javascript..

the best part of Jquery is that u dont need to download the library files in your system thay are hosted on the google server just u need to include it and start owkring..
