A port of Dmitry Chestnykh's typescript blake2s implementation to node.js style javascript

I've left the blake2s.ts script in the source, and edited the output javascript. I did try to bring the typescript to node.js style, using Buffer, update(buffer, enc) but that made a lot of type errors, and in my opinion, type errors are not really the hardest part of programming. I will be happy if someone can show me how to correct the typescript implementation to node.js style.


        // constructor accepts digest length in bytes
var h = new BLAKE2s(32)
        //pass encoding into update, like in node's crypto module
h.update("string or array of bytes", 'utf8')
        //request the digest encoding

// Keyed:
var h = new BLAKE2s(32, "some key")
