Create a Programming Language - Episode 6: Parser and Nodes

Creating a programming language is simpler than you might think. In this series, I am continuing upon the previous one in order to create a better guide to help you create your own language!

In this episode, we make our parser and begin work on our nodes!

27:39 He said the magic words: "type checking". Can't wait to get to that part :D

The perfect exercise in gradual refactoring that starts with a set of classes and slowly turns into struct of arrays that askew polymorphism altogether.

Basically, solving the problem correctly before refactoring it via the "going fast is about doing less" vid on YT = lifechanger!
