Overview of this book

The TypeScript language, compiler, and open source development toolset brings JavaScript development up to the enterprise level. It allows you to use ES5, ES6, and ES7 JavaScript language features today, including classes, interfaces, generics, modules, and more. Its simple typing syntax enables building large, robust applications using object-oriented techniques and industry-standard design principles. This book aims at teaching you how to get up and running with TypeScript development in the most practical way possible. Taking you through two exciting projects built from scratch, you will learn the basics of TypeScript, before progressing to functions, generics, promises, and callbacks. Then, you’ll get to implement object-oriented programming as well as optimize your applications with effective memory management. You’ll also learn to test and secure your applications, before deploying them. Starting with a basic SPA built using Angular, you will progress on to building, maybe, a Chat application or a cool application. You’ll also learn how to use NativeScript to build a cool mobile application. Each of these applications with be explained in detail, allowing you to grasp the concepts fast. By the end of this book, you will have not only built two amazing projects but you will also have the skills necessary to take your development to the next level.

An introduction to the sample Trello application

Our Trello application will be a smaller, trimmed down version of real Trello.

Trello, in the real world, is a task management application, wherein we can group our tasks on different boards, and each high-level task will have multiple subtasks. These subtasks can then be moved to different stages, such as pending, in-progress, and completed. In our sample Trello application, we will not have the latter part, but we will have a dashboard page with multiple boards, so we can drill down into each board to see the tasks and their respective subtasks.
