DEFLATE: used with PNGs, ZIP, gzip

Accept-Encoding:gzip, deflate, sdch, br

more control over processing + memory use

create better tradeoffs

comes with 9 presets for compression

oh, hey use require('zlib')

brotli

brotli:more intune to HTTP compression

comes with a dictionary of commonly used HTML terms

butit's base, it's a bit slower

require('iltorb')

codin o'clock

require('iltorb')

wayyyy slower
