Introduction to Web Assembly

Web Assembly (wasm) is a powerful low-level language that is meant to be a compile target for high-level languages. It is designed to be portable and ran in many different environments. It is designed to compliment JavaScript, not replace it.

Web Assembly runs in its own environment at near native speed, can be cached, and runs much faster than JavaScript can be parsed.

File types

Web Assembly has two file types:

• .wasm is the actual assembly code in binary format
• .wat is the human readable textual representation of the code
