Good way to init array of JavaScript objects and their properties?

Question

I know I can init an array of JS objects like this:

var things = [
  {
    prop1: 'foo',
    prop2: 'bar'
  },
  {
    prop1: 'foo',
    prop2: 'bar'
  }
];

I guess I would call these 'anonymous' types (sorry, I'm using C#/.NET language).

What if I want these to be of the same prototype? So I have defined a constructor:

var Thing = function Thing() {
};

Thing.prototype.prop1 = 'default value';
Thing.prototype.prop2 = 'default value';

Now I want both the items in my original code above to be Things. Is there a good way to do this?

If I were to guess, I would say maybe something like:

var things = [
  new Thing() {
    prop1: 'foo',
    prop2: 'bar'
  },
  new Thing() {
    prop1: 'foo',
    prop2: 'bar'
  }
];

Which is basically C# object initializer syntax. What I'm trying to avoid is:

var thing1 = new Thing();
thing1.prop1 = 'foo';
thing1.prop2 = 'bar';
var thing2 = new Thing();
thing2.prop1 = 'foo';
thing2.prop2 = 'bar';
var things = [thing1, thing2];

Edit:

I should also note that my prototypes also contain some functions that are shared. Also in actuality I have arrays nested 3 deep, so its something more like:

{
   [
    { 
      [
        {},
        {}
      ]
    },
    {
      [
        {},
        {}
      ]
    }
  ]
}

Which is why I as hoping to just init everything inline like this and not setting each property line by line.

Answer 1

var Thing = function(params) {
  this.prop1 = params.prop1;
  this.prop2 = params.prop2;
};

var things = [
  new Thing({
    prop1: 'foo',
    prop2: 'bar'
  }),
  new Thing({
    prop1: 'foo',
    prop2: 'bar'
  }),
];

You are not making use of your 'constructor'. Its preferred to initialize values IN YOUR CONSTRUCTOR:

var Thing = function Thing(prop1, prop2) {
    this.prop1 = prop1;
    this.prop2 = prop2;
};

and then do:

var thing1 = new Thing("foo", "bar");
var thing2 = new Thing("foo", "bar");
