Dear reader,
Thank you for joining us on this learning journey!
As we will discover together throughout the book, the TypeScript programming language can be used to write awesome applications and greatly enhance the developer experience and code quality/safety. TypeScript can be used wherever JavaScript can be, which means practically everywhere. Moreover, TypeScript works wonderfully well with all major libraries and frameworks. Last but not least, it also has a large, vibrant, and enthusiastic community.
With this book, our hope is that we will be able to convince you that TypeScript is a great programming language and that it is relevant whether you are writing frontend applications, backend systems – or whatever else, actually.
Throughout the book, we will give you everything you need in order to acquire a good understanding of how powerful TypeScript really is, how versatile it can be, and how it fits into the modern development puzzle.
But don't take our word for it – we'll show you!
This is a practical book, not a reference guide. We will hold your hand through the journey, but you'll have to roll up your sleeves and get your hands dirty. We strongly believe that learning by doing is the most time-efficient approach to mastering new subjects and this is exactly why we have created this book regarding the TypeScript programming language. In addition, we also love to share our passion for technology and we really hope that you'll enjoy reading this book.
In the first half, we will introduce you to many important features of the TypeScript programming language through exercises and by helping you to create multiple applications. While creating those first applications, you will also learn about many important APIs of the modern web as well as many useful design patterns, techniques, libraries, and tools.
By reading through the chapters and, most importantly, by coding these applications, you'll gain a really good understanding of how TypeScript works and how it fits into the modern software ecosystem.
In the second half of the book, we will continue to teach you about TypeScript features, but our focus will shift to discovering how TypeScript can be combined with some of the most popular libraries and frameworks out there today: Angular, Vue.js, and React. Not only that, but we will also show you how to write backend applications using NestJS, GraphQL, and Apollo.
All of those frameworks and libraries will be explained in the book in enough detail to give you a real taste of how they actually work and without requiring you to do a lot of side research. You'll go from zero to hero in no time!
This book is truly unique; you won't find many others covering so many subjects in a simple, approachable, and cohesive way. Step by step, you'll go from the basics to the more advanced concepts and you'll create cool applications along the way!
