changing a constructor function definition using `functionaName.prototype.constructor`

constructor.js

function Rabbit() {
    this.jumps = "yes";
};

var rabbit = new Rabbit();
console.log(rabbit.jumps);
// Rabbit.prototype.constructor is a pointer to the original constructor `function Rabbit(){..})` so that the users of the class can detect the constructor from an instance
console.log(Rabbit.prototype.constructor);
// outputs exactly the code of the function Rabbit()

function ChangeConstructor() {
    this.jumps = 'no'
}

// Rabbit.prototype.constructor = function Rabbit() {
//     this.jumps = 'no'
// }

Rabbit.prototype.constructor = ChangeConstructor
console.log(rabbit.jumps)

console.log(Rabbit.prototype.constructor)

var a = new Rabbit()
console.log(a.jumps)

// Therefore, when you try to do
Rabbit.prototype.constructor = function Rabbit() {
    this.jumps = "no";
};

// You're just breaking the link between the original constructor and the reference to it on the prototype. So the answer is no, you cannot change a constructor by reassigning to prototype.constructor

console.log(Rabbit.prototype.constructor)
var rabbit2 = new Rabbit();
console.log(rabbit2.jumps)

// How to redefine  a constructor if you really want to redefine a constructor, just do

var oldProto = Rabbit.prototype;
// keeping Rabbit prototype in oldProto variable
Rabbit = function() { // creating a new constructor function with a new definition 
    this.jumps = 'no'
};

Rabbit.prototype = oldProto; // assigning all the prototypes to the new defined Rabbit constructor function prototype

var nn = new Rabbit()
console.log(nn.jumps)
