ترتيب الأرقام بشكل صحيح بإستخدام sort

console.log(JSON.stringify([10, 2, 30].sort()));
console.log(JSON.stringify([10, 2, 30].sort((a, b) => a - b)));

[10,2,30]
[2,10,30]

const numbers = [10, 2, 30];
const ordered = [...numbers].sort((a, b) => b - a);
console.log(JSON.stringify(ordered));
console.log(JSON.stringify(numbers));

[30,10,2]
[10,2,30]
