JetBrains' IDEA (WebStorm if you exclusively touch webdev and nothing more). Great code completion, plugins library, toolset for code handling and VCS, and one of the best merge tools out there. Take quite a bit of RAM and loads longer than VSCode, but on bigger projects totally worth it. Answer from darksparkone on reddit.com

What is a JavaScript compiler?
A JavaScript compiler transforms your JavaScript code into optimized, executable code. Unlike traditional compilers that produce machine code, online JavaScript compilers and editors like PlayCode bundle your code, resolve imports, and transpile modern syntax (ES2026, TypeScript, JSX) into browser-compatible JavaScript that runs instantly. You can compile and edit JavaScript online with zero setup using our JavaScript editor.

VS Code because it's lightweight, fast, expandable, really good extensions, clean and easy to use for all my languages. It's not my first IDE. First was Netbeans or Eclipse or Excel (VBA) not sure about this.

There are a lot of good online IDEs at the moment. One of my favorites is JSFiddle, but you said you don't want to use CSS and HTML so it's superfluous in this case. You can use JSBin, opening only the Javascript and Console panels. Another very good one is, in my opinion, Ideone, which has a lot of languages(for JS you have to select Javascript Spidermonkey). The last one I suggest you is JSConsole, from the creator of JSBin, which is basically an enhanced Javascript console(as the name states).

Have a look at either,
- WebStorm: real JavaScript IDE (possibly the best.)
- Sublime Text 2: text editor with syntax highlighting, and possibility to install plugins.
You can use either software, together with node.js, to get what you want.
Executing the file,
function squareNumber(x) {
return x * x;
}
console.log(squareNumber(5));
with node.js will output,
