Self-references in object literal declarations

How do I do the following:

var object = {
    alpha: 'one',
    beta: **alpha's value**
}

without splitting the object creation into two parts?

Answer 1

You can’t, object literal syntax just doesn’t support this, you’ll have to create a variable first then use it for both, like this:

var value = 'one';
var object = {
  alpha: value,
  beta: value
};

Or…something entirely different, but you can’t reference alpha when doing beta, because neither property has been created yet, not until the object statement runs as a whole is either accessible.
