<p>Is there any way to make something like the following work in JavaScript? </p> <pre class="brush:php;toolbar:false;">var foo = { a: 5, b: 6, c: this.a this.b // Doesn't work };</pre> <p>In its current form, this code obviously throws a reference error because <code>this</code> does not reference <code>foo</code>. But<em>yes</em>Is there any way to make the value in an object literal property dependent on other previously declared properties? </p>

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

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

console.log(foo.c) // 11
