What JavaScript minifier do you recommend?
538
Minification does improve performance for two reasons: Reduced file-size (because it removes comments and unnecessary white spaces), so your script loads faster. Even if it is embedded into the <head> . It is parsed faster, since comments and white spaces don't have to be explicitly ignored (since they're not there).
Since any minification takes server resources, it's worth minimizing only those assets which are relatively unchanging like CSS and JS. HTML changes too frequently to be worth it IMHO.
Minification is the process of minimizing code and markup in your web pages and script files. It's one of the main methods used to reduce load times and bandwidth usage on websites. Minification dramatically improves site speed and accessibility, directly translating into a better user experience.
UglifyJS2, used by the jQuery project.

Google Closure Compiler generally achieves smaller files than YUI Compressor, particularly if you use the advanced mode, which looks worryingly meddlesome to me but has worked well on the one project I've used it on:
Several big projects use UglifyJS, and I've been very impressed with it since switching.

JavaScript Minifier gives a good API you can use programatically:
curl -X POST -s --data-urlencode 'input=$(function() { alert("Hello, World!"); });' http://javascript-minifier.com/raw
Or by uploading a file and redirecting to a new file:
curl -X POST -s --data-urlencode '[email protected]' http://javascript-minifier.com/raw > ready.min.js
Hope that helps.
