What problem are you trying to solve? Javascript can be sent compressed 
if the server and client agree to compressed data transfers, but this is 
a matter to be handled at the io strreaming level, which is not the level 
of the javascript api in the browser.

Moreover, it is singularly dumb to expect javascript to support all the 
historical compression methods of the last 30 years of computing. Most 
operating systems support compression methods by way of library code. 
However, the browser does not expose all system libraries to the script 
engine (except for perhaps msie, and look at all the security issues that 
has caused in the past!).

If you want a generic function to allow scripts executing in your browser 
to call either arbitrary or sandboxed runtime library functions then that 
is the proposal you should be making, but suggesting that javascript 
needs to reinvent the data compression wheel, and moreover that it should 
do so for a whole list of formats which are in most cases redundant, is 
just plain stupid.
