Javascript array variable as "name" not working

Question

I've a javascript variable and running it in my firefox console.

var name = ['manish','google'];
alert(name[0]);

The result of above alert is m

But If rewrite the code as below

var names = ['manish','google'];
alert(names[0]);

Then it alerts manish

Can anyone please let me know that what is the reason behind this?

name is a property of the window object. Check this out

console.log(name); shows that name is recognized as a String not an Array.

Console Output:

manish,google

Use a different variable name if you are in the global scope...

`var` overrules that though. Does it not? – Niet the Dark Absol Feb 10 '16 at 16:03

@Quentin Then this answer is incomplete ;) After all, when I run the code in my IE11 console, it works just fine, presumably because it uses a different scope. – Niet the Dark Absol Feb 10 '16 at 16:05
@Quentin Then why this works fine? var innerHeight = ['manish','google'];alert(innerHeight[0]) – Manish Jangir Feb 10 '16 at 16:11
innerHeight is also a property of window object. Isn't it?? – Manish Jangir Feb 10 '16 at 16:11
`innerHeight` doesn't have a setter function defined behind the scenes to do special stuff when you set it. – Quentin Feb 10 '16 at 16:18
You mean to say, it is restricted to reconfigure with configurable descriptor? – Manish Jangir Feb 10 '16 at 16:21
