Hands-On JavaScript High Performance [Repost]

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.

What you will learn

Explore Vanilla JavaScript for optimizing the DOM, classes, and modules, and querying with jQuery
Understand immutable and mutable code and develop faster web apps
Delve into Svelte.js and use it to build a complete real-time Todo app
Build apps to work offline by caching calls using service workers
Write C++ native code and call the WebAssembly module with JavaScript to run it on a browser
Implement CircleCI for continuous integration in deploying your web apps

This JavaScript book is for web developers, C/C++ programmers, and anyone who wants to build robust web applications using advanced web technologies. This book assumes a good grasp of Vanilla JavaScript and an understanding of web development tools, such as Chrome Developer tools or Mozilla's developer tools.
