Structs in Javascript

The real problem is that structures in a language are supposed to be value types not reference types. The proposed answers suggest using objects (which are reference types) in place of structures. While this can serve its purpose, it sidesteps the point that a programmer would actual want the benefits of using value types (like a primitive) in lieu of reference type. Value types, for one, shouldn't cause memory leaks.

EDIT: There is a proposal in the works to cover this purpose.

//today
var obj = {fname: "Kris", lname: "Kringle"}; //vanilla object
var gifts = ["truck", "doll", "slime"]; //vanilla array

//records and tuples - not possible today
var obj = #{fname: "Buddy", lname: "Hobbs"};
var skills = #["phone calls", "basketball", "gum recycling"];

I always use object literals

{id: 1, speaker:"john", country: "au"}

The only difference between object literals and constructed objects are the properties inherited from the prototype.

var o = {
  'a': 3, 'b': 4,
  'doStuff': function() {
    alert(this.a + this.b);
  }
};
o.doStuff(); // displays: 7

You could make a struct factory.

function makeStruct(names) {
  var names = names.split(' ');
  var count = names.length;
  function constructor() {
    for (var i = 0; i < count; i++) {
      this[names[i]] = arguments[i];
    }
  }
  return constructor;
}

var Item = makeStruct("id speaker country");
var row = new Item(1, 'john', 'au');
alert(row.speaker); // displays: john
