Javascript: Typeerror: ... Is Not A Constructor

I have a TypeError problem: function artist(name) { this.name = name; this.albums = new Array(); this.addAlbum = function(albumName) { for (var i = 0; i < t

Solution 1:

This line

var album = new album(albumName);

shadows the external album function. So yes, album isn't a constructor inside the function. To be more precise it's undefined at this point.

To avoid this kind of problem, I'd suggest naming your "classes" starting with an uppercase :

functionAlbum(name) {

More generally I'd suggest to follow the Google style guide when in doubt.
