Learning TypeScript 2.x - Second Edition

By: Remo H. Jansen

Overview of this book

TypeScript is an open source and cross-platform statically typed superset of JavaScript that compiles to plain JavaScript and runs in any browser or host. This book is a step-by-step guide that will take you through the use and benefits of TypeScript with the help of practical examples. You will start off by understanding the basics as well as the new features of TypeScript 2.x. Then, you will learn how to work with functions and asynchronous programming APIs. You will continue by learning how to resolve runtime issues and how to implement TypeScript applications using the Object-oriented programming (OOP) and functional programming (FP) paradigms. Later, you will automate your development workflow with the help of tools such as Webpack. Towards the end of this book, you will delve into some real-world scenarios by implementing some full-stack TypeScript applications with Node.js, React and Angular as well as how to optimize and test them. Finally, you will be introduced to the internal APIs of the TypeScript compiler, and you will learn how to create custom code analysis tools.

Application Performance

In computer science, a system resource, or simply a resource, is any physical or virtual component of limited availability within a computer system. Every device connected to a computer system is a resource. Every internal system component is also a resource.

In this chapter, we are going to learn how we can manage the available resources of a system efficiently to achieve great application performance. We will learn about the different kinds of resources, performance factors, and performance profiling techniques.

The chapter starts by introducing some core performance concepts, such as latency or bandwidth, and continues showcasing how to measure and monitor performance as part of the continuous integration process.

As we have already learned in previous chapters, we can use TypeScript to generate JavaScript code that can be executed in many different...
