You can create Array of Objects and Arrays of Arrays to structure your 
data, e.g.
  function Planet (name, diameter, moons) {
    this.name = name;
    this.diameter = diameter;
    this.moons = moons;
  }
  function Moon (name, diameter) {
    this.name = name;
    this.diameter = diameter;
  }
  var planets = 
    new Array (
      new Planet('Mecury', 3000, new Array()),
      new Planet('Venus', 7000, new Array()),
      new Planet('Earth', 7000, 
                  new Array(new Moon('Moon', 1000))),
      new Planet('Mars', 4000, new Array())
    );
  alert(planets[0].name);
  alert(planets[2].moons[0].name);
