Overview of this book

If you're looking for a programming language to develop flexible and efficient apps, JavaScript is a great choice. However, while offering real benefits, the complexity of the entire JavaScript ecosystem can be overwhelming. This Workshop is a smarter way to learn JavaScript. It is specifically designed to cut through the noise and help build your JavaScript skills from scratch, while sparking your interest with engaging activities and clear explanations. Starting with explanations of JavaScript's fundamental programming concepts, this book will introduce the key tools, libraries and frameworks that programmers use in everyday development. You will then move on and see how to handle data, control the flow of information in an application, and create custom events. You'll explore the differences between client-side and server-side JavaScript, and expand your knowledge further by studying the different JavaScript development paradigms, including object-oriented and functional programming. By the end of this JavaScript book, you'll have the confidence and skills to tackle real-world JavaScript development problems that reflect the emerging requirements of the modern web.

Performance API

When we're building sites and web apps, it's important to be able to measure the performance of our applications to help ensure good user experiences. We do this during development, testing stages, and in production. As our application grows and we add new features, it's equally important to make sure that the changes we're making aren't negatively affecting performance. There are a number of ways to measure this and some useful tools to help us. One such set of tools is the browser's Performance API and other closely related APIs.

The Performance API allows us to time events with extreme accuracy: the time measurements we have access to are expressed in milliseconds but are accurate to about 5 microseconds. With these APIs, we can accurately measure the time it takes to complete specific actions, such as the following:

  • The time it took to render the first pixel on our page
  • The time between a user clicking an element and...
