get the highest 5 number in an 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 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]));
