js find maximum in 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: 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 3: find highest number in array javascript

function findHighestNumber(nums) {
	
	let inputs = nums.filter((val, i) => nums.indexOf(val) === i)
	let max = Math.max(...nums);
	let min = Math.min(...nums);
  
   return max + (-min);
}

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