Javascript Math max()

Introduction

The Math.max() function returns the largest number of among parameters. 

Math.max([value1[, value2[, ...]]]) // value1, value2, ... are    Numbers.

If at least one of the arguments cannot be converted to a number, NaN is returned. 

let a = Math.max(10, 20);   //  20
console.log(a);//  ww  w.  ja  v a  2  s.  c  om
a = Math.max(-10, -20); // -10
console.log(a);
a = Math.max(-10, 20);  //  20
console.log(a);
let max = Math.max(3, 54, 32, 16);
console.log(max); // 54

The following code uses array.reduce() to find the maximum element in a numeric array: 

var arr = [1,2,3];
var max = arr.reduce(function(a, b) {
     return Math.max(a, b);
});/*from   w ww  .j  av  a2s.c  o m*/
console.log(max);

The following code uses spread operator to get the maximum of an array: 

var arr = [1, 2, 3];
var max = Math.max(...arr);
console.log(max);//from  w w w . ja  v a2  s. c  o  m
