compoo

Simple and basic life-cycle and inheritance JS screwdriver.

How to:

use...

Inheritance

// viola, a class inheriting from Compoo
var Person = Compoo.extend({
  constructor: function (name) {
    this.name = name;
  },
  sayHi: function (personName) {
    console.log("Yo, " + personName + "!");
  }
});

var Dude = Person.extend({
  sayHi: function (otherDude) {
      // notice that you don't need to use Person.prototype
      Person.sayHi.call(this);
      
      console.log("You're the dude of " + otherDude);
  }
});

Instantiation

Normal Compoo way - slower but more conventient from JS point of view:

var thisDude = Person.create();

Classical way with the new keyword - faster but meh...:

var thatDude = new Person.constructor();

Extending Compoo

Extending Compoo via the api object will make Compoo and every derived object inherit the new feature.

Example:

Compoo.api.extend('getName', function () {
  return this.name;
});

will result in:

var person = new Person.constructor('Jon');
person.getName(); // 'Jon'

Mixins

person.implement(
  {jsNinja: true},
  {
    likesJS: function () {
      return true;
    }
  }
);

Cloning

var otherPerson = person.clone({
  name: 'Jacob'
});

Reflection

var person = new Person.constructor();

person.is(Person); // true
person.is(Dude); // false

has instead of hasOwnProperty

person.has('name');
