Regular Expression COmpiler - Compile a regex ahead of time to code
It seems a little weird to me that they start out targeting JS, though. Look at one of the sample generated files -- it has a little comment at the top that has the tiny regex it was generated from. I'd be shocked if that's actually faster -- that's a lot for v8 to parse and optimize, and you're hoping it'll parse/optimize it into better code than it would parsing/optimizing a tiny regex?

Casual Parsing in JavaScript
I’ve found generator functions work great for parsers. You yield the tokens you expect to be next. The token could be a string, a regular expression to be matched, or another generator function.
The library is open source here, contributions welcome: https://github.com/RoyalIcing/yieldparser
Generator functions have great support in modern browsers (not IE) and Node.js.
For example here’s a simple v4 IP address parser:
import { parse, mustEnd } from 'yieldparser';
function* Digit() {
