Tests:
with reduce()
const div = document.getElementById('min-data'); const newArray = []; for(let i = 0; i < 10000000; i++){ const num = Math.floor(Math.random() * 10000000); newArray.push(num); } newArray.reduce((a, b) => (a < b ? a : b), []); div.innerHTML = newArray[0].toString();
with sort()
const div = document.getElementById('min-data'); const newArray = []; for(let i = 0; i < 10000000; i++){ const num = Math.floor(Math.random() * 10000000); newArray.push(num); } newArray.sort((a, b) => a - b); div.innerHTML = newArray[0].toString();
