The Cloud Native Computing Foundation (CNCF) has officially embraced WebAssembly (WASM) as a core technology for modern, cloud-native applications. Originally engineered for high-performance browser workloads, WebAssembly’s secure sandbox, near-native speed, and platform portability now power server-side runtimes and edge computing alike. Hello and welcome to this in-depth WebAssembly course! I’m Mumshad Mannambeth, joined by Nimisha, and together we’ll walk you through hands-on labs, key concepts, and real-world examples so you can become proficient with WASM from day one.
Basic familiarity with JavaScript and command-line tools will help you get the most out of this course.

What You’ll Learn

Below is an overview of the modules we’ll cover. Each section builds on the previous one, so you’ll gain a thorough, end-to-end understanding of WebAssembly in both browser and server contexts.
