Variable as the property name in a JavaScript object literal? [duplicate]

Edit

With ES6, this is now possible using a ComputedPropertyName, which manifests in the form of the following syntax:

var myVar = "name";
var myObject = {
    [myVar]: "value"
};

You can use the [] syntax to use an expression as the property name (compared to the .prop and prop: value syntaxes where they are always treated as strings):

var myObject = {};
var myVar = "name";
myObject[myVar] = "value";

There is no way to use that inside an object literal, though. You have to create the object first and then assign each property separately.
