- How it is used
- Serializes native Python data for outgoing JSON communication and produces JSON strings rather than files.
- How deep it goes
- Defines built-in conversions, demonstrates formatting options, and explains custom-class fallback without detailing encoder internals.
- Examples
- Uses mixed built-in values, formatted dictionaries, sorted keys, and a Task instance converted through __dict__.
- What you can do after
- Apply it via Python's json module to serialize built-ins, format output, and provide fallback handling for custom objects.
