right way to inherit properties in javascript code example

Example: inherit javascript

function Animal() { }
Animal.prototype.eat = function() {
  return "nom nom nom";
};
function Bird() { }

// Inherit all methods from Animal
Bird.prototype = Object.create(Animal.prototype);

// Bird.eat() overrides Animal.eat()
Bird.prototype.eat = function() {
  return "peck peck peck";
};
