JavaScript variable assignments from tuples

Question

In other languages like Python 2 and Python 3, you can define and assign values to a tuple variable, and retrieve their values like this:

tuple = (\"Bob\", 2         


        

Answer 1

Here is a simple Javascript Tuple implementation:

var Tuple = (function () {
   function Tuple(Item1, Item2) {
      var item1 = Item1;
      var item2 = Item2;
      Object.defineProperty(this, "Item1", {
          get: function() { return item1  }
      });
      Object.defineProperty(this, "Item2", {
          get: function() { return item2  }
      });
   }
   return Tuple;
})();

var tuple = new Tuple("Bob", 25); // Instantiation of a new Tuple
var name = tuple.Item1; // Assignment. name will be "Bob"
tuple.Item1 = "Kirk"; // Will not set it. It's immutable.

This is a 2-tuple, however, you could modify my example to support 3,4,5,6 etc. tuples.
