[Interest] Could I use V8 engine directly in QT?

[Max Paperno]

Hi Bob,

What is this v8 you're referring to (in terms of QJSEngine I mean)? Can 
you explain "it used" further?

It's possible, in many/most cases, to extend or even replace the 
built-in JS types in QJSEngine (not QQmlEngine). Either with pure JS 
implementations or C++ or a mix. I'm not sure about adding language 
syntax constructs like async/await though (but you can already use 
Promises, for example).
