Please create js dialog samples (not just ts)

[michhar]

All of the dialog samples are in typescript - could you make some with plain javascript?

Sure... I'll work on that.

@michhar You should be good with these samples up to a point. Just remove the typings, the interfaces, and maybe modify the import statements. If you get stuck, you can review the generated code, which looks like it has been checked into GitHub.
