This chapter addressed the core concepts of how to handle static JSON feeds. We began by importing an external JSON object into our HTML file, and looped through the complex array of objects to parse and extract the required data. We used the while and for
loops to loop through the array and used conditions to target our search. We completed this chapter by locally modifying the existing JSON feed and adding a new property, the employee object. Now that we have mastered accessing JSON from a static file, it is time for us to make some asynchronous calls to fetch some active JSON over HTTP.

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.
