In pursue for my JavaScript code performance and some questions on jQuery mailing list I looked for and eventually came across some of the JavaScript code packers. Here is a list of custom JavaScript code compressors available for free.
- YUI Compressor (from Yahoo)
- JSMin (by Douglas Crockford)
- ShrinkSafe (from Dojo library)
- Packer (by Dean Edwards)
According to general opinion of developers on the net (and jQuery official site) you should use Yahoo's YUI Compressor to compress your jQuery and JavaScript code.
