>>Thank you. Another question. Which IDE did you used with JS at the beginning?

I tried, Eclipse, Aptana with fails some errors. At last tried VS, it tries create Windows 8 store JS application. How can I just create a JS for just run? I don't understand I write a code part in VFP, C# or X++ and run. What a mess with JS...
