Why is "var name" variable initialized as a string when try to initialize it as an array in Javascript?

Question

When I use "name" as a variable name and use var keyword, the "name" variable isn't initialized as array.

var name = ['banana', 'kiwi'];
Object.getPrototypeOf(name) == String.prototype; // true

But when I use const keyword it works normally.

const name = ['banana', 'kiwi'];
Object.getPrototypeOf(name) == Array.prototype; // true

Or when I use a different variable name, it works normally, too.

var name2 = ['banana', 'kiwi'];
Object.getPrototypeOf(name2) == Array.prototype; // true

Why does this happen?
