Find the Difference in Age between Oldest and Youngest Family Members.js

// At the annual family gathering, the family likes to find the oldest living family member’s age and the youngest family member’s age and calculate the difference between them.

// You will be given an array of all the family members' ages, in any order. The ages will be given in whole numbers, so a baby of 5 months, will have an ascribed ‘age’ of 0. Return a new array (a tuple in Python) with [youngest age, oldest age, difference between the youngest and oldest age].

function differenceInAges(ages){
  
    let oldest = 0;
    let youngest = ages[0];
    let res =[];
    
    for(let i = 0; i < ages.length; i++ ){
      
      if(ages[i] > oldest) {
        oldest = ages[i];
      } 
    }
      
    for(let j = 1; j < ages.length; j++) {
      
      if(ages[j] < youngest) {
        youngest = ages[j];
      }
    }
  
    let diff = oldest - youngest;
    res.push(youngest,oldest, diff)
    return res;
