What is JSON?

JSON stands for JavaScript Object Notation,is a lightweight data-interchange format for structuring (representing) data. It is often used by web applications to communicate with each other. It is easy for humans to read and write. The data is in name and value pairs,separated by commas.

It holds objects inside curly braces{}.

💡 Practice Examples:

Example 1. Simple JSON

[
  { 
    "color" : "red", 
    "hex code" : "#FF0000", 
    "rgb code" : "rgb(255, 0, 0)"
  },
  { 
    "color" : "black", 
    "hex code" : "#000000", 
    "rgb code" : "rgb(0, 0, 0)"
  }
]

Example 2. Nested JSON object

[
  {
    "user": {
      "id": 101,
      "name": "Arun Banik",
      "contact": {
        "phone": "+91-9876543210",
        "email": "arun@example.com"
      },
      "roles": [
        "admin",
        "editor"
      ]
    },
    "status": "active"
  }
]

Example 3. MIXED STRUCTURE

  {
    "product": "Laptop",
    "price": 55000,
    "specs": {
      "ram": "16GB",
      "storage": "512GB SSD"
    },
    "available": true
  },
  {
    "product": "Phone",
    "price": 25000,
    "specs": {
      "ram": "8GB",
      "storage": "128GB"
    },
    "available": false
