Rex Tutorial

This tutorial is a guided walk-through of writing Rex code.

All code samples are interactive in the docs, so you can edit and run each snippet as you go.

If you want a compact reference instead, see the Language Reference. For locked semantics and edge cases, see the Specification.

The tutorial is divided into three sections:

• Section 1 — Basics — Core language features and syntax
• Section 2 — Advanced Topics — Type system, polymorphism, and typeclasses
• Section 3 — Worked Examples — Practical examples and patterns
