Javascript Array variable name

Question

I am trying to learn javascript and I just started trying to learn Arrays

I see problem when I use the array name as "name"

var names = ['asdasd','qweqwe'];
names[0];

returns "asdasd"

however,

var name = ['asdasd','qweqwe'];
name[0];

is returning "a"

why is that ? Any help is greatly appreciated.

It's probably in the global scope, so you're really setting window.name, and window.name already exists and can only be a string.

That's what you're returning, the string from window.name, not your name variable.

I don't think window.name is read-only. Rather, assignments to window.name gets converted to a string. So var name = ['asdasd','qweqwe']; results in window.name being asdasd,qweqwe, and name[0] produces the first letter a.

@Antony - that is correct, was going a bit fast there, of course you can name the windows. I changed it.

Thats because name, being a predefined window property is a string and names is an array of string

You may confirm this by printing them individually.

name returns "asdasd,qweqwe" and names returns ["asdasd", "qweqwe"]
