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.

Using VS Code

VS Code is a light and powerful code editor that offers IntelliSense, debugging, source control, task definitions, and other useful features. Different from Visual Studio, VS Code projects do not need a project file to organize all project files or decide how to process the whole project. A VS Code project just consists of all files contained in a folder, and the developers may choose themselves which tools to use to process all the project files and how to configure them. This feature offers great flexibility when developing projects based entirely on TypeScript/JavaScript, since the developer is not constrained by a specific project template but instead may choose the most adequate JavaScript tools for their projects from the thousands of tools available as open source.

This section explores VS Code basics. More specific VS code features will be analyzed in the...
