How to use react memo hooks

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]);
