Don't know if this would really work in JS... but you can use a Object, in which you can store the name and the value:

  function MyLogObject(name, value) {
    this.name = name;
    this.value = value;
  }


  var log = [];
  log.push(new MyLogObject('a', '123'));
  log.push(new MyLogObject('b', 'abc'));
