Code-Based Prototyping: Testing with Dynamic Data

Figma prototypes have inherent boundaries: they cannot store real input state or calculate dynamic mathematical formulas.

When Code Prototyping is Mandatory

• Search & Filter Interfaces: Testing how users behave when filtering a catalog of 10,000 live products.
• Complex Financial Calculators: Where inputs dynamically alter charts and payback periods.
• Screen Reader Testing: Validating whether assistive technologies announce dynamic updates correctly.
