How to use is-number - 5 common examples

function stringDecoding(string) {
  if (string.length === 0) return '';
  let currCount = 0;
  let i = 0;
  let decoding = '';

  while (i < string.length) {
    const char = string.charAt(i);
    if (isNumber(char)) {
      const num = Number(char);
      currCount = currCount * 10 + num;
    } else {
      decoding = addCountAmount(decoding, char, currCount);
      currCount = 0;
    }

    i++;
  }

  return decoding;
}

  hydrate: (txt) => types.cast(txt, 'numeric')
