A pure-JavaScript Inheritance library designed to be easily dropped in to a host library

✔ Pure Javascript (framework-agnostic)
✔ Developer-friendly (enforce usage of native JavaScript functions)
✔ No globals, no native functions enhancements
✔ Tested

Installation

bower install inheritance

Prototypal inheritance

inheritance/prototypal/inherit

Simple Javascript inheritance:

require('inheritance/prototypal/inherit', function(inherit) {

  function Organism() {
    this.alive = true;
  }

  Organism.prototype.isAlive = function() {
    return this.alive;
  };

  function Animal() {
    Animal.parent.apply(this, arguments);
  }
  inherit(Animal, Organism);

  // ---

  new Animal() instanceof Animal; // true
  new Animal() instanceof Organism; // true
  new Animal().isAlive(); // true
  Animal.parent; // Organism

});

inheritance/prototypal/implement

Multiple inheritance through mixins:

require(['inheritance/prototypal/inherit', 'inheritance/prototypal/implement'], function(inherit, implement) {

    function Animal() {
    }

    // Carnivore mixin
    function Carnivore() {
      function eatFlesh(flesh) {
        console.log ('Blurp!');
      }
    }

    function HumanBeing() {
    }
    inherit(HumanBeing, Animal);
    implement(HumanBeing, Carnivore);

    // ---

    new HumanBeing() instanceof HumanBeing; // true
    new HumanBeing() instanceof Animal; // true
    HumanBeing.parent; // Animal
    new HumanBeing().eatFlesh({...}); // 'Blurp!'

  }
);
