Hew Playground vs JavaScript IDE & Node.js

Hew is a programming language built around actors -- lightweight, isolated processes that communicate through messages. If you've ever wondered what safe concurrency looks like without locks, mutexes, or data races, Hew is your answer. Hew Playground puts the full language on your iPhone or iPad. Write real programs in a proper code editor with syntax highlighting, auto-indent, brace matching, and a keyboard accessory bar for quick symbol access. The Hew compiler runs on-device via WebAssembly, so you get live error and warning underlines as you type -- no internet required. Long-press any identifier to see its type. When your code is ready, tap Run to execute it on the Hew server and see output instantly.
