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

Question

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

@RobertHarvey: You really should have announced this somewhere. It caught me totally off-guard and I thought it was bug. (I like it, but it's surprising). – Felix Kling May 12 '14 at 22:10

By the way,, it would be a lot easier to not write duplicate questions if results of what I asked for appeared in search results :/ – GRowing May 12 '14 at 23:35
