Question

I think I may be missing something coming to object reference, in the below case, is this refering to the test object? If not how can I declare b so in the end test.a = test.b ?

test = {
 a: 1,
 b: this.a,
 check : function(){
  console.log(test.a); // returns 1
  console.log(test.b); // returns undefined
 }
};
test.check();

Thanks a lot

You can declare it like this:

function test(){
   this.a = 1;
   this.b = this.a;

    this.check = function(){
       console.log(this.a);  // output 1
       console.log(this.b); // output 1
    }        
}

var t = new test();
t.check();
