Understanding JSON Format
JSON (JavaScript Object Notation) is a lightweight data-interchange format that's easy for humans to read and write, and easy for machines to parse and generate. It's widely used in web applications, APIs, and configuration files. A properly formatted JSON file uses key-value pairs, arrays, and nested objects to represent structured data.

Best Practices for Working with JSON
When working with JSON data, keep these best practices in mind:
- Always validate your JSON before using it in production
- Use consistent formatting for better code maintainability
- Minimize JSON data for production to reduce bandwidth
- Use descriptive key names for better data understanding
