>>>I am very much a newbie to javascript. So I will look up this function; use, upside and downside. One thing I found so far is that javascript is very unforgiving. If I have ANYTHING wrong in my javacript (like, e.g., missing the ending ";") nothing works in the code. And no error appears when I am running it in ASP.NET. I have to be extra careful.

It's a MS add-on for Visual Studio. Easy to get started since it can use your existing .js files - just rename them to .ts. That in itself won't do much but, for example, you can then specify the type for javascript variables and it will enforce type safety.
