const length = Array.isArray(arr) ? arr.length : 0; // or const length = arr?.length ?? 0;
Maybe the first is sort enough and give back result 0 for string too.
Indeed ternary expression are another way to write short and beautiful code. I'll cover it in another article.
const length = arr?.length ?? 0;
is the way to go. why create an empty array when you just want to get 0?
Indeed, this is better, thanks.
