What is the meaning of : for (var key in object)?



A for loop consits of an instant variable, the object being manipulated, and the main body. So when you say,

 for (var key in object) {


var key - is the instant variable
in - refers
object - is the main object which could be a an array or a dictionary.

} - nests the contents of the body of the for loop.

So, yea that's pretty much it. :grin:
