In formal language theory, a context-free language (CFL) is a language generated by a context-free grammar (CFG). Context-free languages have many applications in programming languages, in particular, most arithmetic expressions are generated by context-free grammars. (Wikipedia).
7.1: Intro to Session 7: Context-Free Grammar - Programming with Text
This video introduces Session 7: Context-Free Grammar from the ITP course "Programming from A to Z". A Context-Free Grammar is a set of recursive "replacement" rules to generate text. In this session, I discuss two JavaScript libraries: Tracery and RiTa.js for working with context-free gr

Javascript Scope Tutorial - What Makes Javascript Weird...and Awesome Pt 4
Scope and Context are in every language, but because Javascript is always firing callbacks and running asynchronous tasks, it's easy to lose sight of what scope & context you're in. Scope and context are not the same thing. Scope is variable access - what variables the current piece of c
