Frontend Performance
Why is memoizing a trivially cheap calculation (like x * 2) often counterproductive?

Memoization has a real, guaranteed overhead (dependency comparison, retained memory) — for a cheap enough computation, this overhead can exceed whatever cost it's supposedly avoiding
C
useMemo cannot be used with simple arithmetic
D
