Cómo usar los ganchos de memo React
const computeLetterCount = word => {
let i = 0;
while (i < 1000000000) i++;
return word.length;
};
// Memoize computeLetterCount so it uses cached return value if input array ...
// ... values are the same as last time the function was run.
const letterCount = useMemo(() => computeLetterCount(word), [word]);
