minPrice 처럼 의미가 분명한 변수명을 사용하면 좋을 것 같습니다.

map.set()은 매번 새 배열을 만들어야하니 꺼내서 push 하는 방식은 어떤가요?
| const length = Number(tempStr.slice(0, i)); | ||
| const currentStr = tempStr.slice(i + 1, i + 1 + length); | ||
| result.push(currentStr); | ||
| tempStr = tempStr.slice(length + i + 1); |

slice로 원본을 잘라내면 불필요한 문자열 복사가 반복될 수 있으니 포인터를 만들어서 전진하는 방식도 고려해보면 좋을 것 같아요
