return the largest integer in a array javascript code example

Example 1: get highest value from array javascript

//For Values
var arr =[1,10,3]
var min = Math.min.apply(null, arr),
    max = Math.max.apply(null, arr);

//For Objects
var arr = [{a: 1},{a: 10},{a: 3}]
var values = arr.map(val => val.a);
var max = Math.max.apply(null, values);
console.log(max)

Example 2: find biggest number in javascript array

var peopleData = [ 
    { name: "Paul", height: 180, age: 21 },
    { name: "Johnny", height: 198, age: 43 },
    { name: "Brad", height: 172, age: 49 },
    { name: "Dwayne", height: 166, age: 15 }
];

//Find biggest height number
var maxHeight = 0;

for (var i = 0; i < heights.length; i++) {
    if (peopleData[i].height > maxHeight) {
        maxHeight = peopleData[i].height;
      //if you console.log(maxHeight); you should get 198
    }
}

Example 3: get largest number in array javascript

const array1 = [1, 3, 2];

Math.max(...array1);
// expected output: 3

Example 4: find highest number in array javascript

function findHigestNumber(nums) {
	
	let inputs = nums.filter((val, i) => nums.indexOf(val) === i)
	let max = inputs.length - 1;
	let min = 0;

	for(let i = 0; i < inputs.length; i++) {
      
      if(inputs[i] > max) max = inputs[i];
      if(inputs[i] < min) min = inputs[i];
	}
  
   return max + (-min);
}

console.log(difference([1, 7, 18, -1, -2, 9]));

Example 5: javascript set value to the largest value in an array

//get min/max value of arrays
function getArrayMax(array){
   return Math.max.apply(null, array);
