Question

I am trying to call an object method from an object (the same object) property definition to no avail.

var objectName = {
     method   :   function() {
          return "boop";
     },
     property :   this.method()
};

In this example I want to assign the return value of objectName.method (“boop”) to objectName.property.

I have tried objectName.method(), method(), window.objectName.method(), along with the bracket notation variants of all those as well, ex. this["method"], with no luck.

At initialization this does not refer to the object holding the property method (which is not yet initialized) but to the curent context – and since this has no method property you will get a TypeError.

If it is a custom getter you want, then you might look into using getters and setters in javascript – they are not supported by ECMAscript prior to ES5, but many engines support them nonetheless.
