In the previous chapter, I introduced you to basic JSON, how JSON objects can be embedded into an HTML file, and how basic operations such as accessing keys can be performed on simple JSON objects. Now let us take a step forward and work with JSON objects that are bigger, more complex, and closer to the JSON that we would work with in real-time situations.
