javascript - Self-references in object literal declarations -

-

is there way following work in javascript?

var foo = {     a: 5,     b: 6,     c: this.a + this.b  // doesn't work };

in current form, code throws reference error since this doesn't refer foo. is there way have values in object literal's properties depend on other properties declared earlier?

you like:

var foo = {    a: 5,    b: 6,    init: function() {        this.c = this.a + this.b;        return this;    } }.init();

this kind of 1 time initialization of object.

note assigning return value of init() foo, therefore have return this.
