Interview Prep
Why is memoizing a derived hashmap built from props/state important in a frontend context specifically?
A
It reduces the bundle size

Without it, the (possibly expensive) derivation re-runs on every re-render, not just once, unlike a typical one-shot backend computation
C
It changes the Big-O complexity class of the computation
D
It's only relevant for class components, not function components
