Problem

React Native's Text component had performance issues. It used too many hooks, mounted pressable logic without checking if it was needed, and included redundant context providers that added unnecessary weight to the component tree.

Solution

Fernando Rojo's team rebuilt the Text component by removing unnecessary hooks and reducing context providers. They also made the pressable logic conditional so it only mounts when required.

Impact

The Text component now runs 35% faster. React Native applications see real performance improvements from the leaner rendering and lower computational load.
