Set Object name for variable value

Question

I am curious if it is possible to set the name of an object in Javascript to a variable value. So if I declare a variable objectName and want to create a new object whose name is the value of objectName.

Could you maybe give an example of how you imagine it would work? The description is little vague. — Viele

Try this:

var objectName = "myObjectName"; window[objectName] = { foo: "bar" }; console.log(myObjectName); // { foo: 'bar'}

All global variables are properties of the window object, and since window is an object, we can create a dynamic property using [] syntax. And then you can access it as window.myObjectName, window["myObjectName"] or just plain myObjectName

More info of window object here: http://www.w3schools.com/js/js_window.asp and here https://developer.mozilla.org/es/docs/Web/API/Window/window
