## What it is
Watlings is a collection of small exercises for learning the WebAssembly Text Format (WAT), inspired by Rustlings and Ziglings. Learners fix broken WAT programs and verify solutions via a Node.js CLI, with an optional browser version.

## Use cases
- learn webassembly text format by doing exercises
- practice writing wat programs
- rustlings-style tutorial for wasm
- interactive wasm learning course
- fix small webassembly programs to learn syntax
- browser-based webassembly exercises

## When to choose
- you want hands-on, learn-by-typing practice with WAT rather than reading docs
- you already know some programming and want to pick up WebAssembly fundamentals
- you liked Rustlings or Ziglings and want the same format for wasm

## When to avoid
- you need a production WebAssembly compiler or runtime toolchain
- you want comprehensive wasm documentation or reference material rather than exercises
- you cannot install Node.js 23+ and wasm-tools
