Unexpected typeof value for number variable in JavaScript

I was just randomly practicing JS code today and I put this line of code and ran the code. 

var name = 45;
console.log(typeof name);

It told me the type of variable name is a string. It's very strange but type of Name is String yet when I typed this: 

var age = 45;
console.log(typeof age);

But here type of variable age is Number. Why am I observing this kind of inconsistency? is it some convention or something like this?

If you were running this in a browser, then I think it's because the default execution context is the window object. Basically, every global value you declare becomes a property of the window object, and vice versa: every property of the window object is available as a global variable (e.g console). Window objects have a name property by default, and redeclaring it as a variable doesn't affect that. Anyway, that's the closest I can get to an explanation.
