Question

I have a simple problem with array, i can’t solved.

Example : http://jsfiddle.net/8jyUT/

Why second console.log can’t display the array correctly ?

(I’m on Chrome)

Answer 1

It’s logging the array but it seems empty, because you didn’t populate it numerically ( which is how arrays should be populated ). You can still access the name property of the array,

var albums = new Array();
var album = new Array();
album['name'] = 'This is War';
albums.push(album);

console.log(albums);            
console.log(albums[0].name);​

in JS, Any object can have properties, and arrays are objects. If you have no use for numerical ordering for the album nor any of the array methods, then use an object and not an array:

var albums = [], album = {};
album['name'] = 'Test';
albums.push(album)

console.log(albums);            
console.log(albums[0].name);​
