Watlings

Watlings is an educational platform designed to teach WebAssembly concepts through interactive, browser-based exercises that guide users step by step in learning the WebAssembly text format (WAT). Inspired by projects like Rustlings, it provides a collection of small, focused challenges that help users understand how WebAssembly works at a low level, including instructions, memory management, and control flow. Each exercise presents partially completed code that the user must fix or complete, reinforcing learning through hands-on problem solving rather than passive reading. The platform runs entirely in the browser, allowing users to experiment with WAT code and see immediate results without installing any tools. It is particularly useful for developers who want to understand how high-level languages compile down to WebAssembly or who are interested in systems-level programming concepts.
