## AI overview

Figma describes replacing the decade-old Instance Updater architecture for component instances with a reactive foundation. The change made common operations in large design systems up to 50% faster and supports more dynamic features as components become more complex.

## Source excerpt

By replacing a decade-old architecture with a reactive foundation, we made common operations in large design systems up to 50% faster and unlocked a new way to build dynamic features.
