extend-it

A Javascript helper for creating a subclass that extends from a super class. It uses Object.create() internally to achieve classical inheritance. This is for single inheritance, which is all what JavaScript (<ES6) supports.

Installation

npm install extend-it --save

Usage

var extend = require('extend-it');

function Shape(xPos,yPos) {
  this.x = xPos;
  this.y = yPos;
}

// Rectangle extend Shape
var Rectangle = extend(Shape);

// new instance of Rectangle
var rectangle = new Rectangle(1, 2);

// check the properties inherited from Shape
console.log(rectangle.x);
console.log(rectangle.y);

Tests

npm test
