How is JSON Used?

JSON serves as the language of the internet. It is primarily used for **Data Interchange** between a server and a web application.

1. Serialization

Serialization is the process of converting a data structure or object into a JSON string so it can be stored or transmitted.

const jsonString = JSON.stringify(userObject);

2. Deserialization (Parsing)

When an app receives a JSON string from an API, it parses it back into a native object to access the data.

const user = JSON.parse(receivedString);

3. Common Implementations

  • AJAX Requests: Fetching data without reloading the page.
  • Webhooks: Sending real-time notifications between servers.
  • NoSQL Storage: Storing data in flexible document formats.
