Array Literal Syntax

[Temedyos]

Hello every one

 

may some one can help me in this issue. When I use Literal syntax for Array like this:

 

var name = ['name1', 'name2', 'name3', 'name4'];

alert(name[2]);

 

it return to characters in Array, but when i use it like this way:

 

 

var names = ['name1', 'name2', 'name3', 'name4'];

alert(names[2]);

 

it return to the name3 at full not just one character on it.

 

So my question is, there any point i miss to learn about this technique, or it could be problem in language ?

In programming, you most often start the count at zero. names[2] is therefor the third element in the array. ('name3')

 

This can be a little confusing at first.

I'm guessing you're using Chrome, right?

You're having this problem because "name" is a global variable attached to the window object, which can be referenced in Chrome using just "name".

Ah! Lovely cross-browser issues, huh?

 

Anyway, here's a more complete answer:

Just don't use the name "name" (or any other keyword for that matter) for a global variable name, and you'll be fine.

 

Edit: It's not surprising that you haven't heard of it. I didn't know about it either until you brought it up and I played with it a bit.

Part of the problem with browsers like Chrome and FF constantly being silently updated is that things like this get introduced with little to no documentation, or worse, little to no knowledge of this cross-browser issue by the developers themselves.

I guess some prudence always pays off. If any variable name with the exception of "name" works fine, then I guess you know it's an issue with that variable name (for whatever reason).
