Me again.

I know nothing about web programming but it's time I did and looking at the wapp examples see html and javascript, in them.

I know people build websites with html, javascript (with or without frameworks) and css.

I'm not trying to be awkward, I'm trying to understand.... What, precisely, is wapp bringing to the party, that gives you an advantage??? I.e. what's its big value add.

Any advice, much appreciated.
