array min and max code example

Example 1: max value in array javascript

// For large data, it's better to use reduce. Supose arr has a large data in this case:
const arr = [1, 5, 3, 5, 2];
const max = arr.reduce((a, b) => { return Math.max(a, b) });

// For arrays with relatively few elements you can use apply: 
const max = Math.max.apply(null, arr);

// or spread operator:
const max = Math.max(...arr);

Example 2: find min and max date in array javascript

const dates = [];
dates.push(new Date('2011/06/25'));
dates.push(new Date('2011/06/26'));
dates.push(new Date('2011/06/27'));
dates.push(new Date('2011/06/28'));
const maxDate = new Date(Math.max.apply(null, dates));
const minDate = new Date(Math.min.apply(null, dates));
