JavaScript Super global variable?

Question

With ECMA6 where does this variable stand?
Var? Obviously not let. Not constant either.

Answer 1

This is old style js syntax, where 'var' could be omitted. If you add "use strict" at the beginning, such syntax will be disabled and you get error displayed.

Answer 2

I'm not sure exactly what the question is, but the variable "someVar" is considered a global variable. It is a part of window, meaning you could also write console.log(window.someVar) to get the same results.
