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.

Chapter 4

  1. Protected members can be used by successor classes, while private members can't. No, abstract members can't be declarated private, otherwise no successor could provide a definition for them.
  2. When the method doesn't use this.
  3. Yes, classes may have several constructor overloads. They are defined like function overloads.
  4. No, it is not possible because abstract classes are incomplete.
  5. Yes, abstract classes can also have constructors. Abstract class constructors can be called by successor classes to initialize properties of the abstract class.
  6. By preceding the method with super.
  7. By calling super(<parent constructor arguments>) in its constructor.
  8. Write-only properties can be defined with setters.
  9. When several classes have some common methods but implement them in different ways. This way, they may be processed uniformly by the same chunks of code that...
