WASM

ELI5 — The Vibe Check

WASM is the cool abbreviation for WebAssembly, because saying the full name every time would take longer than the code takes to execute. It's the binary format that makes browsers go brrr.

Real Talk

The common abbreviation for WebAssembly. WASM refers to both the binary format (.wasm files) and the ecosystem of tools and runtimes (like Wasmtime, Wasmer) that execute WebAssembly modules in browsers and server-side environments.

When You'll Hear This

"Ship the WASM binary — it's half the size of the JavaScript equivalent." / "WASI is bringing WASM to the server side, and it's going to change everything."
