Seems I didn't understand the constructor concept, So, I wrote some code to test it. Say you have the code like this:
var test=function(){...}
I know there is a property named constructor in the test.prototype object which point to the test object.
Here comes my question:
Is this property(constructor) only belongs to the prototype object ? or Do all the objects have the constructor property?
And I did another test. the code like below:
function Shape() {
this.x = 0;
this.y = 0;
}
Shape.prototype.move = function(x, y) {
this.x += x;
this.y += y;
console.info("Shape moved.");
};
Rectangle = Object.create(Shape);//inherit from the Shape instead of Shape.prototype
Rectangle.constructor==Function//it is true.
I don't know where does Rectangle.constuctor come from or does it inherit from the Shape? thanks.
