Javascript dead code elimination

I'm looking for a way to reduce a javascript library/framework with the objective of only sending to the client (browser) only the necessary code. I've searched and I found that, for example, closure compiler can't remove jquery dead code.

How can I write a web application, using javascript or any other languages/frameworks/tools to archive this goal? I've nothing against frameworks but in mobile devices performance counts a lot. I've tested HTML5 mobile apps on cheap android devices and it's terrible to use due to performance issues. I want to extract maximum performance.

My 2 cents:

In term of performance, use good practises with a linter such as jslint, jshint, or eslint.

To check wich concept is better than another one, you can check at jsperf or make your own ones with benchmark.js.

For loading time, jQuery is a bit big for mobile. Zepto is a good alternative. Imo, it's better to concat all js files on mobile than async load the js.

MicroJs is a site which list all libraries that usually fit a specific need.
