What is JSON?

JSON, short for Javascript Object Notation, is a way for developers to store data in an organized and easy to read manner. It is mainly used for transfering data from a server to the webpage or used in APIs to transfer and display data from the server. JSON is made up of a collection of key-value pairs.

Storing JSON Data

As mentioned earlier, JSON uses key-value pairs to organize and store data. Here's an example:

  • name: "Jason"
  • gender: "male"
  • age: "20"
  • country: "United States"

As can be seen from the example above, the data consists of key-value pairs where the value can be a string, integer, boolean, or another nested JSON data.
