How can I create an online Javascript compiler to compile and execute Javascript real-time online? I'm building an interactive Javascript editor using Monaco editor but need ideas for compiler and real time output. Some ideas I have is an express app with babel compiler and use vm2 to run the code? Any more sophisticated ideas?

October 2, 2025 - JavaScript (JS) is a lightweight interpreted (or just-in-time compiled) programming language with first-class functions. While it is most well-known as the scripting language for Web pages, many non-browser environments also use it, such as Node.js, Apache CouchDB and Adobe Acrobat.

Modern runtimes work - more or less - by compiling as much JS as they can to native code, so I can't imagine AOT compiler would give that much benefits. Dynamic nature of the language has some cost, unfortunately.

As far as I know, there are no static compilers for JavaScript. It is certainly theoretically possible; however, a static compilation of JavaScript would need a very heavyweight runtime to support all of its features (such as dynamic typing and eval). As a small aside, when presented with the need to statically compile Python (another dynamic language), the PyPy developers ended up creating a language which was a very restricted subset of Python (called RPython), void of some of Python's more dynamic features, that was capable of being statically compiled.
If you're asking this for the purpose of creating a standalone executable from JavaScript code, I'm sure there must be wrappers which essentially would create an executable containing your script and an embedded JavaScript VM (sadly, I don't know any offhand).

It's definitely doable, although the only way I know how to do it at the moment is a two step process...
- Compile the javascript to Java using Mozilla Rhino JSC.
- Compile the resulting java class file to executable using something like GNU's GCJ.
Why would you want to, though? What advantage do you expect to find?

November 3, 2021 - TypeScript - VS Code has great support for TypeScript, which brings structure and strong typing to your JavaScript code. VS Code supports JSX and React Native. You will get IntelliSense for React/JSX and React Native from automatically downloaded type declaration (typings) files from the npmjs type declaration file repository. Additionally, you can install the popular React Native extension from the Marketplace. To enable ES6 import statements for React Native, you need to set the allowSyntheticDefaultImports compiler option to true.
