<나의 풀이>

function solution(s) {
    const arr = ["zero","one","two","three","four","five","six","seven","eight","nine"]
    for(let i = 0; i< arr.length;i++) {
        s = s.replaceAll(arr[i],i)
    }
    return Number(s);
}

<다른 사람의 풀이>

const solution = (s) => {
  const wordsMap = {
    zero: 0,
    one: 1,
    two: 2,
    three: 3,
    four: 4,
    five: 5,
    six: 6,
    seven: 7,
    eight: 8,
    nine: 9,
  };

  let words = Object.keys(wordsMap);

  words.forEach((e, i) => {
    while (s.includes(e)) {
      s = s.replace(e, wordsMap[e]);
    }
  });

  return +s;
