map function for objects (instead of arrays)
I have an object:
myObject = { 'a': 1, 'b': 2, 'c': 3 }
I am looking for a native method, similar to Array.prototype.map that would be used as follows:
newObject = myObject.map(function (value, label) {
return value * value;
});
// newObject is now { 'a': 1, 'b': 4, 'c': 9 }
Does JavaScript have such a map function for objects? (I want this for Node.JS, so I don't care about cross-browser issues.)
