Best browser based code editor?
For absolute beginners, probably Codepen. For more complex projects where you have multiple files, CodeSandbox. More on reddit.com

what's your favorite code editor app?
I use vscode for my dev. I do embedded Linux development on an Ubuntu VM using the remove SSH extension which is amazing. I also use it for everything else, python scripting on the VM, or windows, and even some stm32 development on windows. More on reddit.com

Anyone know of a 100% browser based IDE?
https://vscode.dev/ is basically VS Code running inside a browser. But from what I know about using it, it still uses local file system access for the actual files. And of course, you'd still have to compile and run the code locally, so that's not going to work for you. And that's part of the problem: an IDE is a tool for writing code and even compiling it, but the code still runs on your computer, not inside an IDE. And the IDE interacts with things like a compiler, and might even install it along with the IDE, but it's usually a separate program (like javac for Java). You can get some practice using sites like https://replit.com/ or https://ideone.com/ , but you're probably not going to build big/real projects there. More on reddit.com

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.
