- Why are symbols so useful for metadata handling?
- What is a well-known symbol?
- What is Symbol.Iterator needed for?
- What TypeScript instruction is specific to iterables?
- What is the advantage of generator functions over defining iterators directly?
- Can TypeScript generate equivalent code for browsers that do not support iterables?
- What is the advantage of Map<T> over indexable types (please refer to the Indexable types subsection of Chapter 2, Complex Types and Functions)?
- How do Promises improve the classic callback pattern for handling asynchronous operations? In turn, how do the async/await patterns improve the standard usage of Promises?

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.
