Node.js playground FAQ

Can I require npm packages?

No. Keep snippets self-contained. Use local Node for package experiments; use Toolliyo for learning loops.

Is this the same as the JavaScript compiler?

Same engine, Node-oriented samples and SEO — so backend learners find it quickly from the Compilers menu.

Do I need an account?

No. Run is free and rate-limited.
