how to use javascript Object.defineProperty

Question

I looked around for how to use the Object.defineProperty method, but couldn\'t find anything decent.

Someone gave me this snippet of code:

Object.def         


        

Answer 1

Basically, defineProperty is a method that takes in 3 parameters - an object, a property, and a descriptor. What is happening in this particular call is the "health" property of the player object is getting assigned to 10 plus 15 times that player object's level.
