Serialization and Deserialization In JavaScript

The concept of serialization and deserialization is mainly used to efficiently store and transmit data.

In JavaScript, it is used to convert data into JSON format and bring it back to its original structure.

Serialization

Serialization means converting any data structure (like an object or array) into a string format so that it can be easily transmitted or stored. In JavaScript, we use JSON.stringify() for serialization.

Serialization = Ordering Food on Swiggy/Zomato! 🍔📦

Imagine you are a restaurant owner, and a customer orders a burger for delivery. You can’t send the burger as it is; you need to package it properly before sending it.

Step 1: Packing the Burger (Serialization)

• You prepare a fresh burger 🍔
• You pack it in a box 📦
• You label the box with customer details (name, address, order ID, etc.) 🏷️
• You hand it over to the delivery person 🚴‍♂️

Now, the burger is in a structured format, ready to be sent anywhere. This is Serialization!

{
  "item": "Burger",
  "price": 150,
  "customer": {
    "name": "Rahul",
    "address": "Delhi",
    "contact": "9876543210"
  }
}

✅ Now the data is in a structured format (JSON), which can be easily processed by any system (like Swiggy/Zomato).

Deserialization

Deserialization means converting serialized data (string) back into its original form (object/array). For this, we use the JSON.parse() function.

Step 2: Customer Opens the Box (Deserialization)

• When the order reaches the customer, they don’t eat the burger directly
• First, they open the box 📦
