JSON Introduction

JSON stands for JavaScript Object Notation

• a file format for data storage and data exchange

JSON stores two types of data

1. An object
2. An Array of values

Object

An object starts with left curly brace { and ends with a right curly brace }.

Inside of an object, the dictionary is formed by pairs of property names and values.

Each property is separated from each other by a comma ,.

The property names and property values are separated by a colon :.

{
    "name": "John", 
    "age": 30 
}

Array of values

An array is a list of values, and values can take many forms:

• string surrounded by double quotes "Hello World!"
• number 12345
• object { "name": "David" }
• array []
• true
• false
• null

Example

{
   "employees":[
      {
         "name":"Shyam",
         "email":"shyamjaiswal@gmail.com"
      },
      {
         "name":"Bob",
         "email":"bob32@gmail.com"
      },
      {
         "name":"Jai",
         "email":"jai87@gmail.com"
      }
   ]
}
