Text compiler

<aside> 💡 Type system - a set of rules that a typechecker uses to assign types to your program.

Errors are surfaced at compile time.

TS- statically typed. Gradually typed.

JS - dynamically typed. Weakly typed.

Code editor setup

I'm going to be using emacs and i-know i already have tide installed. What other setup do I need to do?

Interesting, following the example tsconfig I got an error because console wasn’t included in es2015 lib, had to add DOM for that to work.
