Passing Objects When we copy an object or pass an object to a function, it is often passed a reference to that object. So we make any changes to the object's references, which in effect will affect the original object of the reference.var she = {num:1}; var her =// 1her.num =+// The same is true for passing objects to functions:var she = {num:1}; var function (o) {o.num=100= 100;Compare
