How to print the top 3 largest values from array in JavaScript

Answer 1

function printTop3(arr) {
    let first, second, third;
    const len = arr.length;
 
    if (len < 3) {
        return;
    }
  
    first = second = third = Number.MIN_VALUE;
     
    for (let i = 0; i < len; i++) {
        if (arr[i] > first) {
            third = second;
            second = first;
            first = arr[i];
        }
        else if (arr[i] > second) {
            third = second;
            second = arr[i];
        }
        else if (arr[i] > third)
            third = arr[i];
    }
  
    console.log(first + " " + second + " "  + third);
}
  
const arr = [ 12, 98, 80, 50, 88, 35, 70, 60, 97, 85, 89 ];
      
printTop3(arr);
 
   
     
     
/*
