javascript get array min and max

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);
10

1//get min/max value of arrays
2function getArrayMax(array){
3   return Math.max.apply(null, array);
4}
5function getArrayMin(array){
6   return Math.min.apply(null, array);
7}
8var ages=[11, 54, 32, 92];
9var maxAge=getArrayMax(ages); //92
10var minAge=getArrayMin(ages); //11

7const minDate = new Date(Math.min.apply(null, dates));
