How 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.

r/learnjavascript on Reddit: Free online tool to test out javascript?
March 5, 2025 -
Hi guys
I'm looking for a free online tool where I can practice HTML, CSS and Javascript. I prefer something with an console included so that I can see my error messages right away. playcode.io is pretty great, but requires a subscribtion if you write more than a certain amount of code. Do you known of other similar solutions where I can see the console as well? I've been using https://onecompiler.com/ which lacks the console : (
Thanks!
