JSON Key

The key is always on the left side of the colon in a key/value pair. It must be a string and enclosed in double quotes (") according to the official JSON standard. It provides context for the value it's associated with.

Best Practices for Keys

• Be Descriptive: Use clear names like "firstName" instead of ambiguous ones like "fn".
• Be Consistent: Stick to a single naming convention, such as camelCase (e.g., "userName") or snake_case (e.g., "user_name").
