JavaScript Anywhere - Offline JavaScript Runner

App crashes and doesn’t recognize my “prompt” attribute. Says it’s an error. Run it on another app, works fine. Like I said, needs work.

Running on iPad pro and iOS 11. Won’t even stay open for several minutes without bombing out and quitting. Useless.

Not sure what it's capabilities are, like is it using the Safari JavaScript engine to execute the code or does it have it's own proprietary interpreter? Seems to get the job done though.

Hope you can emulate ES6

Wow, the easiness and simplicity of this iPad app is amazing, it makes writing quick JavaScript easy and efficient.
