find max and min value in array javascript

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);

1Math.max(1, 2, 3)    // 3
2Math.min(1, 2, 3)    // 1

4var nums = [1, 2, 3]
5Math.min(...nums)    // 1
6Math.max(...nums)    // 3
