Content of this folder follows zlib C sources as close as possible.
|
That's intended to simplify maintainability and guarantee equal API
|
and result.
|
|
Key differences:
|
|
- Everything is in JavaScript.
|
- No platform-dependent blocks.
|
- Some things like crc32 rewritten to keep size small and make JIT
|
work better.
|
- Some code is different due missed features in JS (macros, pointers,
|
structures, header files)
|
- Specific API methods are not implemented (see notes in root readme)
|
|
This port is based on zlib 1.2.8.
|
|
This port is under zlib license (see below) with contribution and addition of javascript
