new Map<string,number> 이런식으로 타입을 지정해주어도 좋을거같아요!

for (let i = 0; i < s.length; i++) {
map.set(s[i], (map.get(s[i]) || 0) + 1);
}
for (let i = 0; i < t.length; i++) {
if (!map.has(t[i])) {
return false;
}
const newCount = map.get(t[i]) - 1;
if (newCount < 0) return false;
if (newCount === 0) map.delete(t[i]);
else map.set(t[i], map.get(t[i]) - 1);
}

return map.size === 0;
}
