JSON (JavaScript Object Notation) is a lightweight data format that’s easy for both humans to read and machines to process. It organises information in a structured way using key-value pairs and arrays, making it ideal for sending data between web servers and browsers. For example, a simple JSON file might store customer data like this: {“name”: “John Smith”, “email”: “john@email.com“, “age”: 30}.
