1.

답안1)

-문자열 -> 배열 : split("") 

-reverse()

-배열 -> 문자열 : join("")

function solution(my_string) {
  //1.split()
  let splitedString = my_string.split(""); //문자열을 끊은 다음 -> 배열로 return

  //2.reverse()
  let reversedArray = splitedString.reverse();

  //3.join()
  let answer = reversedArray.join(""); //배열 -> 문자열

  return answer;
}

console.log(solution("jaron"));
