Какой код лучше?
1)
const countChar = (x, y) => {
return x.split('').map(_ => _ === y).reduce((acc, i) => acc + i);
}
console.log(countChar('jjjhjjjhjjj', 'j')); -> 9
//////////////////
2)
function countChar(string, ch) {
let counted = 0;
for (let i = 0; i < string.length; i++) {
if (string[i] == ch) {
counted += 1;
}
}
return counted;
}

Я тебе могу сказать какой быстрее
