What are the JavaScript compilers or interpreters available for Windows?
I read the book Eloquent JavaScript recently.
I also had the same need but eventually found an app called DeskJS (https://deskjs.wordpress.com). It's a free and portable Windows console application that lets you run pure JavaScript code and even load any existing JS files. It supports the basic JS popup boxes implemented in browsers. You can save your commands as JS files that can be run on startup or by dragging-and-dropping them on the app. Plus there's so much more to it like you can create a build system for Sublime Text that can run JS files via cmd, it supports themes for customizing the entire console and snippets which let you save short snippets of JavaScript code for later use. Improvements are still being made on the app together with other native APIs being included.
