Overview of this book

Are you are looking for a better, more efficient, and more powerful way of building front-end web applications? Well, look no further, you have come to the right place! This book comprehensively integrates Angular version 4 into your tool belt, then runs you through all the new options you now have on hand for your web apps without bogging you down. The frameworks, tools, and libraries mentioned here will make your work productive and minimize the friction usually associated with building server-side web applications. Starting off with building blocks of Angular version 4, we gradually move into integrating TypeScript and ES6. You will get confident in building single page applications and using Angular for prototyping components. You will then move on to building web services and full-stack web application using ASP.NET WebAPI. Finally, you will learn the development process focused on rapid delivery and testability for all application layers.

Preface

Inheritance


Inheritance is the concept of inheriting some behaviors of another class or object. It helps achieve code reusability and build hierarchy in relationships of classes or objects. Also, inheritance helps you cast similar classes.

JavaScript of ES5 standard doesn't support classes, and so, class inheritance is not possible in JavaScript. However, we can implement prototype inheritance instead of class inheritance. Let's see inheritance in ES5 with examples.

First, create a function named Animal, as follows. Here, we create a function named Animal with two methods: sleep and eat:

var Animal = function() { 
    this.sleep = function() { 
       console.log('sleeping'); 
    } 
    this.eat = function() { 
       console.log('eating'); 
    } 
} 

Now, let's extend this Animal function using the prototype, as shown:

Animal.prototype.bark = function() { 
    console.log('barking'); 
} 

Now, we can create an instance of Animal and call the extended function bark, as demonstrated:

var a = new...
