Minifier
A JavaScript minifier has three components:
- printer
- mangler
- compressor
Mangler
The mangler implementation is part of the SymbolTable residing in oxc_semantic.
It is responsible for shortening variables. Its algorithm should be gzip friendly.
The printer is also responsible for printing out the shortened variable names.
Compressor
The compressor is responsible for rewriting statements and expressions for minimal text output. Terser is a good place to start for learning the fundamentals.
