Use variable for property name in JavaScript literal?

Is it possible to add a variable as the property name of an object in JavaScript, like this:

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

Answer 1

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.

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" }; 

Answer 2

Like this?

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