Since the rise in popularity of the XMLHttpRequest
object, it has become a boon for web developers. In this chapter, we began with the basics, such as what we need to make an AJAX request. Furthermore, we moved ahead and understood the basic concept of how an XMLHttpRequest
object is responsible for making an asynchronous request. Then we took a leap into one of the most powerful JavaScript Libraries, jQuery, to perform AJAX operations using jQuery. This is just the beginning of our journey into AJAX; in the next chapter, we will be looking at more complex cases where AJAX is used, the cases where cross-domain asynchronous requests fail, and how JSON saves the day by allowing us to make cross-domain asynchronous calls.

Overview of this book
JSON is an established and standard format used to exchange data. This book shows how JSON plays different roles in full web development through examples. By the end of this book, you'll have a new perspective on providing solutions for your applications and handling their complexities.
After establishing a strong basic foundation with JSON, you'll learn to build frontend apps by creating a carousel. Next, you'll learn to implement JSON with Angular 5, Node.js, template embedding, and composer.json in PHP. This book will also help you implement Hapi.js (known for its JSON-configurable architecture) for server-side scripting.
You'll learn to implement JSON for real-time apps using Kafka, as well as how to implement JSON for a task runner, and for MongoDB BSON storage. The book ends with some case studies on JSON formats to help you sharpen your creativity by exploring futuristic JSON implementations. By the end of the book, you'll be up and running with all the essential features of JSON and JavaScript and able to build fast, scalable, and efficient web applications.
