  Move is a subset of JavaScript [...] The following three examples are all valid Move code while the last one is also valid JavaScript code

You keep using that word. I do not think it means what you think it means.

It says subset in the title and superset in the description.

I think it is more accurately described as a superset of javascript, Just as C++ is(nt) a superset of C.

Or as Objective-C is a superset of C.

It is neither. It is another language which can be interpreted from JS through a library.

The difference in the semantics of «==» is an example. Also, it does not have things that JS has, and has other things JS doesn't.
