What is JSON? Explained with JSON Examples!

Let’s get to the JSON structure. { "Actors": [ { "id": "1", "firstName": "Tom", "lastName": "Cruise" }, { "id": "2", "firstName": "James", "lastName": "Bond" } ] }

This example shows the Actors’ data and has two actors. It’s easy to understand along with that it takes less space to store in memory than XML.

Above JSON data consists of an array of Actors and each actor is value in JSON Array. Looks complicated?

Let’s understand all the data type JSON has, to represent the data.

JSON Data Types

• Number
• String
• Boolean
• Array
• Object
• Null

This example uses all the JSON data types.

{ "id": 1, "age": 30, "Name": "James Bond", "Address" :[ { "city":"Los Angels", "country": "USA" }, { "city":"London", "country": "UK" } ], "wife":null, "ishavingmobile":true, "firstmovie" :{ "name":"Dr. No", "releaseyear":1962 }   }
