How to reference a key from the same object when creating it?

Question

Say I have an object such as this:

var time = {
    \'second\': 1000,
    \'minute\': 1000 * 60,
    \'hour\'  : 1000 * 60 * 60,
    \'day\'   : 1000 * 60 *          


        

Answer 1

Change the object to a constructor function and you can do this:

function Time() {
    this.second = 1000;
    this.minute = this.second * 60;
    this.hour = this.minute * 60;
    this.day = this.hour * 24;
    this.week = this.day * 7;
}

// Use
var time = new Time();
