Chapter 1. Getting Started with JSON

JSON (JavaScript Object Notation) is a very popular data interchange format. It was discovered by Sir Douglas Crockford. According to Douglas, JSON always existed in terms of object notation, so he didn't invent it. He was the first person to provide the specifications and engineer JSON so that it can be used as a standardized format.

In this chapter, we are going to cover the following topics:

  • What JSON is
  • How JSON is implemented using a simple Hello World program
  • How JSON is stored in memory
  • Datatypes in JSON
  • Various languages that support JSON
  • PHP and Python explained in brief

Now for all the beginners, who have just heard the term JSON for the first time, the following section helps to visualize it in detail.
