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.
