我如何将名字和数字的和分开？

function separateNameAndNumber(input) {
  let name = '';
  let number = '';

  for (let i = 0; i < input.length; i++) {
    if (!isNaN(input[i])) {
      number += input[i];
    } else {
      name += input[i];
    }
  }

  return {
    name: name,
    number: number
  };
}

const inputString = 'John123';
const result = separateNameAndNumber(inputString);
console.log('Name:', result.name);
console.log('Number:', result.number);
