find max from array javascript 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: 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

Example 4: Find the maximum number of an array js

Math.max(10, 20);   //  20
Math.max(-10, -20); // -10
Math.max(-10, 20);  //  20
