Array of Generic Objects - adding data into

Hello

I seek correction and guidancem from you experts, on the Associative arrays and the arrays of Generic Objects.

I created the following working code and I believe it is an Associative array:

var arrColors: Array = new Array();
arrColors.push({color: "aqua", code: "0x00FFFF"});
arrColors.push({color: "beige", code: "0xF5F5DC"});
arrColors.push({color: "brown", code: "0xA52A2A"});
// and so on ..... 

Now, I want to create an array of Generic Objects for the same items, as below:

var obj: Object = new Object();
obj["key"] = "value";

But, I don’t know how to add more than one items in the above array.

Would an expert help, please!
