Javascript : Creating object with dynamic property

Question

I want to write a function which returns an object that will contain a property based on a parameter of the function.

Something like

var my_object_creator = function(prop, value) {
    return { prop: value }
}

But the value of the property should not be "prop", but to evaluate the value of prop, and this is the property name.

I know I can do it like this

 var my_object_creator = function(prop, value) {
    var t =  {};
    t[prop] = value;
    return t;
}

But I'm wondering whether there's a more elegant way.

Thanks

In ES2015:

return { [prop]: value };
