#4Sort of similar to this base64 encoder I wrote to speed up ThreeJS float data streams. Seems more complex though that the stuff that I did.
I had good performance gains versus JSON as evidenced by this popular JSPref:

That's a definite possibility. We went with base-94 because it avoids UTF-8 overhead in situations where the browser will treat your data as a string (e.g. no typed-array support). We also wanted copy/paste to work, and for Flotsam data to be embeddable into JSON with minimal expansion.

Could you elaborate? I don't see the application, JS is still ghastly slow in comparison to C.

#8Do the performance gains depend on how many digits before or after the decimal point there are?

#9This is a problem that only "walled garden" languages like Java and JavaScript would ever even have in the first place. If you're not trapped in a gilded cage, you just print raw bytes directly to a socket and then read data back the same way. The only concern is byte ordering, which is easy.
Regarding this specific approach, "only 20% overhead" sounds pretty good, but base 64 encoding has "only 33% overhead", is completely general, and likely already has faster implementations than this.

Compile to asm.js?
Right then why would you ever even use this library instead of a typed byte array? ASM.JS isn't needed for typed arrays, besides its only supported on FF.
