title: Way to implement better regex in Node.js
body: <p>I'm using Node.js for a project, and I'm finding Javascript's regex syntax very limiting. Specifically the lack of lookbehind is killing me. I'm trying to use regex to parse strings into sentences, but I want to check for common abbreviations such as Mr. and Mrs. so that I don't break the sentences up. Is their a Node.js library that adds regex features, and if not what would a good course of action be?</p>
