Zstd: pure javascript implementation

[cordovapolymer]

Any chance that a pure JS implementation will be developed?
There's a https://github.com/kig/zstd-emscripten port, but it looks like unmaintained.

Indeed, this version appears unmaintained.
We are welcoming any new JS port (or binding).

@Cyan4973 Two JS bingings already exist, it would be great to have a pure JS port.

It's not the same as downloading a pure Javascript source code implementing zstd,
but for information, this blog entry explains how to create zstd for browser using emscripten :

Hello, I wrote above blog entry, and creating a new zstd binding powered by Emscripten (pure-js).

• Github repository
• NPM

This binding work on both Node.js and Browser.
Browser example:

Nice work @yoshihitoh !

I guess @yoshihitoh port, now also referenced on Zstandard homepage, is a nice answer to this request.

Some work along these lines was done recently for ITK.
