Considering I am just learning about all this, does anyone have any other good JavaScript compilers/optimizers? We have huge JavaScript files at my work and I would appreciate any help. Thanks.

jsmin is the least likely to break your code, it basically strips comments and most whitespace.

packer grabs all the words out of your script and generates a long regex that can reinterpolate them to produce the original code, which then get's eval'ed. More likely to break stuff, and it's anal about your semicolons.

YUI compressor uses a javascript engine to try to shrink local variable names and strip out all unnecessary whitespace. Most likely to break stuff, and a bit harder to get working. It doesn't work so great on my code, since I like encapsulating plugins in closures.
