proto-proper.js NPM Package

ISC License

A generic & helpful prototype object upon which new prototypes can be based.

The Proto object provided by this library contains functions useful for prototype creation, manipulation, inheritance, and the retrieval of useful information about a prototype.

Don't know much about prototypal based object-oriented programming or want to understand it better? Prototypal Object-Oriented Programming using JavaScript by Mehdi Maujood is an excellent, short article from A List Apart which is a great starting point for understanding prototypal based OOP and how it is/can be used in JavaScript.

MyObject.init = function(options) { ... };
MyObject.func0 = function() { ... };

Inheritance From a Custom Prototype

MyObject.init = function(options) { ... };
MyObject.func0 = function() { ... };
 
let MyChildObject = MyObject.newPrototype();

API Docs

Proto

Type: Object

Extends: Object.prototype

A generic prototype upon which new prototypes can be based.

This object contains functions useful for prototype creation, manipulation, inheritance, and for obtaining useful information about a prototype.


Proto.newPrototype()

TODO: Add description

Returns: TODO: Add description

Example Usage:

let Parent = Proto.newPrototype();
// add stuff to Parent
 
let Child  = Parent.newPrototype();
// add stuff to Child

Proto.new([...arguments])

Creates a new instance of this prototype.

This function is to be called instead of using the new keyword.

Any arguments passed to this function will be used as the arguments for the call made to the init function.

Returns: A newly created and initialized instance of this prototype.

Example Usage:

let MyObject = Proto.newPrototype();
// add stuff to MyObject
 
let obj = MyObject.new();

Proto.init([...arguments])

Initializes object.

This function is called whenever new() is called and can be seen as the "constructor" of the prototype.


Proto.instanceOf(proto)

A helper function to determine whether or not an object is a prototype/instance of any given prototype (proto).

Parameters:

  • proto [Object] - The prototype object being searched for in the prototype chain.

Returns: true if the given proto is found in the prototype chain of the object; otherwise, returns false.

Example Usage:

let Parent = Proto.newPrototype();
let Child  = Parent.newPrototype();
 
let parentObj = Parent.new();
let childObj  = Child.new();
 
Parent.instanceOf(Object); // returns `false`
Child.instanceOf(Object);  // returns `false`
 
parentObj.instanceOf(Object); // returns `false`
childObj.instanceOf(Object);  // returns `false`
 
Parent.instanceOf(Parent);           // returns `true`
Parent.instanceOf(Proto);            // returns `true`
Parent.instanceOf(Object.prototype); // returns `true`
 
Child.instanceOf(Child);            // returns `true`
Child.instanceOf(Parent);           // returns `true`
Child.instanceOf(Proto);            // returns `true`
Child.instanceOf(Object.prototype); // returns `true`
 
parentObj.instanceOf(parentObj);        // returns `true`
parentObj.instanceOf(Parent);           // returns `true`
parentObj.instanceOf(Proto);            // returns `true`
parentObj.instanceOf(Object.prototype); // returns `true`
 
childObj.instanceOf(childObj);         // returns `true`
childObj.instanceOf(Child);            // returns `true`
childObj.instanceOf(Parent);           // returns `true`
childObj.instanceOf(Proto);            // returns `true`
childObj.instanceOf(Object.prototype); // returns `true`
