Why is it impossible to change constructor function from prototype?

Question

I have such example.

function Rabbit() {
    var jumps = \"yes\";
};
var rabbit = new Rabbit();
alert(rabbit.jumps);                    // undefined
alert(Ra         


        

Answer 1

Try the following

function Rabbit() {
  this.jumps = "no";
};

var rabbit = new Rabbit();
alert(rabbit.jumps);  // Prints "no"
