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.

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.

Are you guys aware of any good online JAVA IDE that supports coding suggestions and error corrections highlighting like Visual studio code?
I have very old Macbook pro (2011 edition) that does not support latest Visual studio code and as Im trying to learn Java on my own, I am looking for any online alternatives for writing and testing any java code or program that works just as well as Visual studio code.
Thank you in advance and have a good weekend.
