# Course Introduction

> This article introduces a course on WebAssembly, covering key concepts, hands-on labs, and real-world examples for proficiency in WASM.

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.

## 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.

| Module                | Topics Covered                                                                                   |
| --------------------- | ------------------------------------------------------------------------------------------------ |
| Introduction to WASM  | What is WebAssembly, core benefits, primary use cases, JavaScript comparison, end-of-lesson quiz |
| WASM Architecture     | Module structure, instruction set, value types, linear memory, tables, globals                   |
| Binary & Text Formats | `.wasm` binary format vs WAT text format, WASI overview, creating and loading a browser module   |
| Compiling to WASM     | Emscripten for C/C++, wasm-pack for Rust, debugging strategies                                   |
| JavaScript API        | Instantiating modules, memory management, function imports/exports, integration patterns         |
