What is the best way to practice html/CSS?
Learn by doing. Html and css isn't something you really learn out of a book or with a couple exercises. It is a lot of repetition to learn css properties, selectors, units etc. A good way to practice is to create personal projects. Personal Blog Wordpress Theme Calender App Etc. If you really wanna start small I suggest going to a random css gallery(for example cssmania.com) taking a website there and just recreating it bit by bit. This is a good way to learn decent html/css markup. If you keep doing this you will see patterns emerge that you can re-use and make your own. A good place to build a website would just be op your own pc. Just open a text editor or code editor, save your website with a .html extension and open it with your favourite browser.

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.

What is a JavaScript compiler?
A JavaScript compiler transforms your JavaScript code into optimized, executable code. Unlike traditional compilers that produce machine code, JS compilers like PlayCode bundle your code, resolve imports, and transpile modern syntax (ES2026, TypeScript, JSX) into browser-compatible JavaScript that runs instantly.

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.
