JSON

JSON (JavaScript Object Notation) is a text-based data format used for exchanging data between applications. It is easy to read and write and can be easily processed by machines.

Functionality and Use

JSON is frequently used in websites and apps to transfer data between the client (e.g., a browser) and the server. It serves as a structured representation of data that can be understood by both sides. It can also be used on the server side in combination with other technologies, such as Node.js.

It is often used as an alternative to XML and is particularly common in combination with JavaScript. At the same time, JSON is language-independent and can also be used with programming languages such as Python, Java, or C++.

Examples

• Transferring product data between the browser and the server, such as product names and prices in an online store
• Loading user data between the app and the server
• Retrieving up-to-date data from the server, such as weather information
• Updating content without reloading the page, such as social media feeds
