Is there a way to create and run javascript in Chrome?

Question

Is there a way, like an extension or application, in Chrome to create and run .js files in Chrome?

Answer 1

Try this:
1. Install Node.js from https://nodejs.org/
2. Place your JavaScript code into a .js file (e.g. someCode.js)
3. Open a cmd shell (or Terminal on Mac) and use Node's Read-Eval-Print-Loop (REPL) to execute someCode.js like this:
> node someCode.js

Hope this helps!
