Dynamically create OBJECTS NAME in javascript/jquery, NOT it’s keys or values

How can you create an object with a dynamically created NAME?
NOT dynamically created keys or values.
I’d like to learn this in both jQuery and javascript

var com = "thing_"
var bined = "one"
var [com+bined] = {}

//so I can populate as such:
thing_one.key = value

I’ve googled my eyes out and tried a thousand things. Thanks in advance and apologies if I overlooked the obvious.
