useState for one-time initializations

Read Original

This React article discusses the pitfalls of using useMemo for one-time resource initialization in components, as React may discard memoized values. It presents a real-world example of creating a resource instance and explains why useState with a function initializer is the correct pattern for ensuring stable, one-time initialization that persists across re-renders.
