Overview of this book

High-performance web development is all about cutting through the complexities in different layers of a web app and building services and APIs that improve the speed and performance of your apps on the browser. With emerging web technologies, building scalable websites and sustainable web apps is smoother than ever. This book starts by taking you through the web frontend, popular web development practices, and the latest version of ES and JavaScript. You'll work with Node.js and learn how to build web apps without a framework. The book consists of three hands-on examples that help you understand JavaScript applications at both the server-side and the client-side using Node.js and Svelte.js. Each chapter covers modern techniques such as DOM manipulation and V8 engine optimization to strengthen your understanding of the web. Finally, you’ll delve into advanced topics such as CI/CD and how you can harness their capabilities to speed up your web development dramatically. By the end of this web development book, you'll have understood how the JavaScript landscape has evolved, not just for the frontend but also for the backend, and be ready to use new tools and techniques to solve common web problems.

Summary

In this chapter, we learned how to read and write WebAssembly. We also gained an understanding of how programs are understood by typical computers. On top of this, we wrote a program that is able to utilize this near-native speed. Finally, we took a look at an existing WebAssembly program and how that relates to the code it was generated from.

By now, we have learned quite a bit about the web development landscape. We have looked at coding in the browser and how we can utilize all of the new features to create feature-rich web applications. On top of this, we have seen how JavaScript can be used as our server-side code utilizing Node.js. Finally, we took a look at how to build and deploy our applications. By now, we should be comfortable building scalable applications and utilizing many of the modern features to create blazing fast applications.
