Write your own language and file parsers in Javascript

Overview and examples how to parse your own custom language, or how to create e.g. your own CSV/XML parser for your special parsing needs. We'll go through some of the practical approaches you can use, while almost fully ignoring (often boring and overly complex) formal language parsing terminology. You'll see that string parsing in Javascript is easier than you might have thought, and also can be more performant than often is talked about.

Why me? I've written my own JSON Query language, https://github.com/TeeAaTeeUu/JSONway , and an avid do-it-yourself developer with minimal external libraries or dependencies.
