WebAssembly (WASM) is a binary instruction format that runs in modern web browsers and beyond, enabling developers to build fast, portable, and secure applications. It allows code written in languages like C, C++, Rust, and Go to run alongside JavaScript, unlocking near-native performance for compute-intensive tasks. WASM is now widely used in web, server, cloud, blockchain, and edge computing environments.
This course introduces learners to WebAssembly fundamentals, toolchains, integrations, and real-world applications. By the end, you’ll be able to compile code to WASM, run it in the browser, and integrate it with modern web and backend platforms.

1. What is WebAssembly (WASM)?
A binary instruction format that runs in web browsers and other runtimes, enabling near-native performance.
2. How does WASM differ from JavaScript?
WASM is compiled to a low-level binary for performance, while JavaScript is interpreted. They often work together.
3. What languages can compile to WASM?
Rust, C, C++, Go, AssemblyScript, and more.
4. What is WASI?
The WebAssembly System Interface, enabling WASM to run outside browsers (e.g., servers, CLI apps).
5. How does WASM improve performance?
By running compiled code directly in a secure sandbox with near-native execution speed.
6. Can WASM access native device APIs?
Not directly; it interacts via host environments like JavaScript or WASI.
7. What are common use cases for WASM?
Web apps (games, ML), blockchain smart contracts, edge computing, and AI workloads.
8. What are the benefits of WASM?
-
High performance
-
Cross-platform portability
-
Secure sandboxing
-
Multi-language support
9. What are challenges with WASM?
-
Limited direct DOM access
-
Debugging complexity
-
Still evolving ecosystem
10. Where is WASM being adopted?
