pwValidation.ts

const validatePassword = (pw: string) => {
  const minimumLength = 5;
  const amountOfCriteria = 1;

  const isLongEnough = (pw: string) => pw.length >= minimumLength;
  const containsDigit = (pw: string) => (
    [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
      .some(n => pw.includes(String(n)))
  );

  return Array.of(isLongEnough, containsDigit)
    .map(f => f(pw))
    .filter(fulfilled => fulfilled)
