You might not need jQuery (2014)
It's ironic that there's probably no bigger sales pitch for jQuery than this site.In every single example, the jQuery version is basically one or two lines of code, versus 10-15 lines for the alternative. (and the jQ version seems significantly easier on the eyes as well.)Also, jQuery supports promises and has for quite a while.This page hasn't aged well. I've come full circle and am now using jQuery again.
