Javascript Emulator Needed

Hi guys,
I need a good Emulator for my Javascript code.
This is needed to help know my errors before uploading to VoltBuilder
Help is much appreciated in advanced.

Do you need to test any plugins?

Yes to test both plugins and Javascript code before bringing over to Voltbuilder

Since plugins only run on devices, you’ll have to test any code involving them after you build with VoltBuilder. Fortunately, it’s easy to debug apps on Android devices using the Remote Debugger.

Code that does not involve plugins can still tested on the desktop, just like any JavaScript code.
