What is the best code editor/runner for Javascript [beginner]?
You dont need "the best code editor". You need the basic understanding of how your code is executed. Sure, some editors might give you easy ways to start a live web server or run your script with node or w/e, but that shouldn't be imporant in this case. Create an index.html and main.js empty files. You can open these files in any editor, even notepad (to prove a point) In your HTML file have the More on reddit.com

January 6, 2014Choosing the best WYSIWYG editor: Slate vs Quill vs ProseMirror.
I'm getting into ProseMirror at the moment. Its document model is more advanced and flexible than Quill. The Quill author admitted this in some HN comments. Even today Quill cannot produce nested lists and fakes it with CSS.
So far ProseMirror is very deep and flexible, but low level and tedious. Atlassian built an utils library to help with this.
Since I'm working with Vue on my current project I haven't really spent much time at looking into Slate, but it seems very interesting and well done. I'm still evaluating ProseMirror, but I'd try Slate next if it doesn't work out for me.

April 7, 2017How 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.

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.

August 7, 2025 -
I just started learning JavaScript but I wanted to learn it and use it with real code editors already to get used to it better. After some research I downloaded VScode, I have absolutely no idea what I'm doing, how do you see if your code is working on VScode?? (I believe it's called running a code?)
I'd love advice too please!

You dont need "the best code editor". You need the basic understanding of how your code is executed. Sure, some editors might give you easy ways to start a live web server or run your script with node or w/e, but that shouldn't be imporant in this case. Create an index.html and main.js empty files. You can open these files in any editor, even notepad (to prove a point) In your HTML file have the tag. Then you can double click on the html file to open it in the browser, and your main.js code will execute. This is the most common begginer entrypoint for someone learning front-end javascript. Alternatively, install node and run your code with node main.js in the terminal (html not needed), but this will not run in the context of a browser.
