July 13, 2019How fast is the online JavaScript compiler?
PlayCode's compiler is optimized for speed. Initial compilation takes 100-500ms depending on project size. Incremental builds (when you edit code) complete in 20-50ms. That's often faster than running a local Node.js bundler because everything runs in memory with no disk I/O.

Does the JavaScript compiler work offline?
PlayCode works offline once loaded. The compiler runs entirely in your browser using WebAssembly, so you can keep coding without an internet connection. Your code is saved locally and syncs when you're back online.

What is a JavaScript compiler?
A JavaScript compiler transforms your JavaScript code into optimized, executable code. Unlike traditional compilers that produce machine code, JS compilers like PlayCode bundle your code, resolve imports, and transpile modern syntax (ES2026, TypeScript, JSX) into browser-compatible JavaScript that runs instantly.
