Creating objects in JS

Question

I am trying to create objects in JS for the first time (for a game engine), but I am not able to establish the properties. I have the following code:

function door(x, y, goto, key) {
    this.x = x;
    this.y = y;
    this.goto = goto;
    this.key = key;
}

But, when I call the function

var door1 = door(1,2,3,4);

It says 'x' does not exist. I have done some experiments changing variables names, and it refers to 'this.x', not the xi pass as a parameter. Does anyone know how can I set the value?

var door1 = new door(1,2,3,4);
