The Super Tiny Compiler

Welcome to The Super Tiny Compiler!

This is an ultra-simplified example of all the major pieces of a modern compiler written in easy to read JavaScript.

Reading through the guided code will help you learn about how most compilers work from end to end.

Why should I care?

That's fair, most people don't really have to think about compilers in their day jobs. However, compilers are all around you, tons of the tools you use are based on concepts borrowed from compilers.

But compilers are scary!

Yes, they are. But that's our fault (the people who write compilers), we've taken something that is reasonably straightforward and made it so scary that most think of it as this totally unapproachable thing that only the nerdiest of the nerds are able to understand.

Okay so where do I begin?

Awesome! Head on over to the the-super-tiny-compiler.js file.

I'm back, that didn't make sense

Ouch, I'm really sorry. Let me know how it can be improved.

Tests

Run with node test.js

What is this?The Super Tiny Compiler is an ultra-simplified, heavily-commented example of all the major pieces of a modern compiler, written in plain JavaScript so beginners can learn how compilers actually work.
Is this a library I install, or something I just read?It is not a reusable library; it is a single guided source file meant to be read line by line to understand compiler internals.
How do I start going through it?Open the-super-tiny-compiler.js in the repo and read through the annotated code; there is also a Glitch version if you want to try it in the browser first.
Do I need anything installed to follow along?Just Node.js is needed to run the included tests; no other dependencies are listed.
Is this meant to be used as a real compiler in a project?No, it is explicitly a teaching example meant to demystify compilers, not a production compiler tool.
What's the point of learning about compilers if I don't write them at work?The project argues that compiler concepts show up constantly in everyday dev tools even if you never build a compiler yourself, which is why understanding the basics is worth it.
What if the code still doesn't make sense after reading it?The author explicitly invites feedback, saying to let them know how the explanation can be improved if it doesn't click the first time.
Can I try it without cloning the repo?Yes, there's a Glitch link in the README that lets you check out and run the code directly in the browser.
