Chapter 1, Introduction to TypeScript, introduced the TypeScript union of simple types as a simple way of retaining the flexibility of JavaScript variables after the addition of strong typing. Type unions are also easily extended to all the types we describe in this chapter, including arrays, tuples, and interfaces, and to all types that will be introduced in the remainder of the book. However, in the case of more complex types, such as interfaces, we can also define the intersection of types. In fact, while it is hard to imagine a meaning for the intersection of, say, number and string, it would be quite spontaneous to define the intersection of two interfaces as a type that keeps all prescriptions of both interfaces. For instance, the intersection of Person with PhysicalObject should be a type that is both Person and PhysicalObject; that is, a type that contains...

Overview of this book
Writing clean, object-oriented code in JavaScript gets trickier and complex as the size of the project grows. This is where Typescript comes into the picture; it lets you write pure object-oriented code with ease, giving it the upper hand over JavaScript. This book introduces you to basic TypeScript concepts by gradually modifying standard JavaScript code, which makes learning TypeScript easy for C# ASP.NET developers.
As you progress through the chapters, you'll cover object programming concepts, such as classes, interfaces, and generics, and understand how they are related to, and similar in, both ES6 and C#. You will also learn how to use bundlers like WebPack to package your code and other resources. The book explains all concepts using practical examples of ASP.NET Core projects, and reusable TypeScript libraries. Finally, you'll explore the features that TypeScript inherits from either ES6 or C#, or both of them, such as Symbols, Iterables, Promises, and Decorators.
By the end of the book, you'll be able to apply all TypeScript concepts to understand the Angular framework better, and you'll have become comfortable with the way in which modules, components, and services are defined and used in Angular. You'll also have gained a good understanding of all the features included in the Angular/ASP.NET Core Visual Studio project template.
