I can see a reason  unrelated to the original post  to automatically compile jQuery code into standard JavaScript   16k -- or whatever the gzipped  minified jQuery library is -- might be too much for your website that is intended for a mobile browser   The w3c is recommending that all HTTP requests for mobile websites should be a maximum of 20k   w3c specs for mobile  So I enjoy coding in my nice  terse  chained jQuery   But now I need to optimize for mobile   Should I really go back and do the difficult  tedious work of rewriting all the helper functions I used in the jQuery library   Or is there some kind of convenient app that will help me recompile   That would be very sweet   Sadly  I don t think such a thing exists

The easiest way is to just learn how to do DOM traversing and manipulation with the plain DOM api  you would probably call this  normal JavaScript     This can however be a pain for some things   which is why libraries were invented in the first place    Googling for  javascript DOM traversing manipulation  should present you with plenty of helpful  and some less helpful  resources   The articles on this website are pretty good  http   www htmlgoodies com primers jsp   And as Nosredna points out in the comments  be sure to test in all browsers  because now jQuery won t be handling the inconsistencies for you

This will get you 90  of the way there      window     document querySelectorAll bind document    For Ajax  the Fetch API is now supported on the current version of every major browser   For   ready    DOMContentLoaded has near universal support   You Might Not Need jQuery gives equivalent native methods for other common jQuery functions     Zepto offers similar functionality but weighs in at 10K zipped   There are custom Ajax builds for jQuery and Zepto as well as some micro frameworks  but jQuery Zepto have solid support and 10KB is only  1 second on a 56K modem
