Overview of this book

If you want to improve responsiveness or the UX in your ASP.NET applications, JavaScript can be a life saver. In an age where server-side operations have shifted to the client, being able to handle JavaScript with confidence and fluency is vital for ASP.NET developers. There’s no point trying to fight it, so start learning with this book. Make sure your projects exceed user expectations. Begin by getting stuck into the basics of JavaScript, and explore the language in the context of ASP.NET Core. You’ll then find out how to put the principles into practice, as you learn how to develop a basic ASP.NET application using Angular 2 and TypeScript. You’ll also develop essential skills required to develop responsive apps, with a little help from AJAX, ensuring that you’re building projects that can be easily accessed across different devices. With guidance on Node.js and some neat techniques to test and debug a range of JavaScript libraries in Visual Studio, you’ll soon be well on your way to combining JavaScript with ASP.NET in a way that’s capable of meeting the challenges of modern web development head-on.

Object-oriented programming in JavaScript


All the objects in JavaScript are inherited from an object. JavaScript provides different patterns to adhere to the object-oriented programming (OOP) principles when building applications. There are different patterns, such as constructor patterns, prototype patterns, and object literal representation, and, with ECMAScript 6, a completely new way of representing objects through classes and inheriting a base class using the extends keyword.

In this section, we will see how we can implement the OOP principles with different methodologies.

Creating objects

A class represents the structure of an object and every class has certain methods and properties used by the object, whereas an object is an instance of a class and is known as a class instance.

JavaScript is a prototype-based language and based on objects. In a class-based language such as C# and Java, we have to first define the class that contains some methods and properties and then use its constructor...
