1// For large data, it's better to use reduce. Supose arr has a large data in this case:
2const arr = [1, 5, 3, 5, 2];
3const max = arr.reduce((a, b) => { return Math.max(a, b) });
4
5// For arrays with relatively few elements you can use apply: 
6const max = Math.max.apply(null, arr);
7
8// or spread operator:
9const max = Math.max(...arr);
