Using external JSON files

What is this skill?

Using external JSON files involves loading data from separate .json files into your prototype, enabling realistic datasets for testing search, lists, and data-driven features.

Why is it important?

• Realistic data – Test with representative datasets
• Separation of concerns – Keep data separate from templates
• Easy updates – Modify data without changing code
• Large datasets – Handle more data than would be practical inline
