how to find max indexes of elements in array js code example

Example 1: how to find index of max number in js

var a = [0, 21, 22, 7];
var indexOfMaxValue = a.reduce((iMax, x, i, arr) => x > arr[iMax] ? i : iMax, 0);

document.write("indexOfMaxValue = " + indexOfMaxValue); // prints "indexOfMaxValue = 2"

Example 2: get max element of array javascript

const maxMinArray = (a,b,...c) =>{
    //we are concatinating this array
    let array = [a,b];
    let newArray = array.concat(c);
    //now let's get started with the excersice
    let max = 0;
    for(let number of newArray){
        if(max<number){
            max = number;
        }
    }
    let min = max;
    for(let number of newArray){
        if(number<min){
            min = number;
        }
    }
    return console.log(max + ' ' + min)
}
//example: 
maxMinArray(12,14,15,23)

Example 3: js max value of array

let numbers = [4, 13, 27, 0, -5]; // Get max value of an array in Javascript

Math.max.apply(null, numbers); // returns 27

Example 4: max element in array

int max;
max=INT_MIN;

for(int i=0;i<ar.length();i++){
	if(ar[i]>max){
    	max=ar[i];
    }
