— They're tagged pointers carrying the name of the variable, too

— 

So yes... you would be able to look at this during run time if we are provided an abstraction to the hash property

— You could look into the future, man

— And know, somewhere ahead of the current executing statement, there is a variable being declared but not allocated yet (due to not being executed yet)

— You could perhaps, at the top of your functions, get a list of all the variables being declared

— This is especially powerful after a function finished executing too, since if you use that abstraction on a function after the fact, you could also see the same information from the outside

— How to prevent the zoom in website ? f.e :- facebook.com on android browser. any tip pls ?

— It is perhaps default behaviour of js, hoisting

— Exactly, this is how hoisting works

— Currently JS provides us with very inconsistent ways of determining if a variable is undeclared versus unassigned... you are forced into relying on a reference error

— But the parser knows... if we had some abstraction like the hash thing, we could know

— It would mean so much for debugging and monitoring of scopes
