javascript - Is there a way to remove a whole property from a js object

I presume this is an odd question but I have to ask..

If I have a js object that looks like this:

$scope.obj1 = {
    "name":"John",
    "number":"Eleven",
    "color":"Red"
}

Is there a way to remove an entire property? without re-assigning values to a new object.. So if I want to get rid of "number":"Eleven", I would like the object to look like this...

$scope.obj1 = {

    "name":"John",
    "color":"Red"
}

Thanks!

JavaScript has a delete operator:

delete $scope.obj1.number
