TypeScript - Instantiating New Objects

Notice the difference here. Method 1 is standard. Method 2 differs a little that it would from c#. Notice that you instantiate the anonymous object, you do not use the new keyword like you would with c#. You also use a colon instead of a equal operator.

// method 1
let thing1 = new Thing();
thing1.Property1 = "Foo";
thing1.Property2 = "Bar";
thing1.Property3 = "undecided";

// method 2
let thing2: Thing =
{
    Property1: "Foo2",
    Property2: "Bar2",
    Property3: "undecided2",
};

// c# method
Spaceship oSpaceship = new Spaceship()
{
    PassengerCapacity = 10,
    RequiredCrew = 5
};
