javascript max value array 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 the maximum number of an array js

var arr = [1, 2, 3];
var max = arr.reduce(function(a, b) {
  return Math.max(a, b);
});

Example 3: how to return the max and min of an array in javascript

function minMax(arr) {
  return [Math.min(...arr), Math.max(...arr)];
}

Example 4: find max and min value in array javascript

var numbers = [1, 2, 3, 4];
Math.max(...numbers) // 4
Math.min(...numbers) // 1

Example 5: Math max with array js

var nums = [1, 2, 3]
Math.min.apply(Math, nums)    // 1
Math.max.apply(Math, nums)    // 3
Math.min.apply(null, nums)    // 1
Math.max.apply(null, nums)    // 3
