Frontend Performance
A code review finds a heavy date-picker library wrapped in dynamic() with no loading fallback, used in a form field most users interact with within the first few seconds of landing on the page. What should be flagged?
A
Nothing — dynamic() is always the correct choice
B
Two issues: splitting a component nearly all users trigger quickly likely worsens perceived latency, AND the missing loading fallback means users see a blank gap rather than any feedback during the unavoidable delay
C
Only the missing loading fallback is a real issue
D
dynamic() cannot be used with form components
