Math being one of my least favorite subjects, I assumed I'd be bored or it would be over my head.

Instead, I'm half way into chapter 3 -- will be sharing! Thank you for this great work!

Thanks for your kind words! Most math textbooks are packed with formulas and abstract stuff, so I tried to do something different, make it fun while still getting the ideas across. Hope you like it!

Interesting project. I'm quite interested in developing a small programming language myself, but am not sure where to start. What resources do you recommend?

Crafting Interpreters https://craftinginterpreters.com is a super friendly, step-by-step guide to building your own language and VM, looking forward to seeing what kind of language you come up with too!

We’ve been building Mochi, a small statically typed language for querying structured data like JSON, CSV, and in-memory lists. In the latest release (v0.10.5), you can write SQL/LINQ-style queries with from, where, join, and group by, all fully type-checked and testable inline.

What makes it different: queries compile to a register-based bytecode VM (written in Go) with compiler passes like constant folding, liveness analysis, and dead code elimination. It’s meant to feel like writing SQL inside a real language, backed by actual compiler infrastructure.

If you’re interested in how query engines, DSLs, or virtual machines work, this might be worth exploring.
