NumberFlow

NumberFlow is Maxwell Barvian's React component for animating numbers: when the value changes, each digit rolls to its new position while the formatting stays correct. It formats through Intl.NumberFormat with locales, prefixes and suffixes, offers trend and per-digit controls for cases like countdowns, and respects the reduced-motion preference by default. It has no dependencies, and its docs are worth reading for how much care a single counter can take.
