Reduce Function

 let arr=[6,5,32,12];

let val=arr.reduce((res,el)=>{
console.log(res);
return res+el;
});
console.log(val);


// Using reduce find the max in an array
let nums = [12, 3, 4, 65, 71];
let ans = nums.reduce((max, el) => {
  if (max < el) {
    return el;
  } else {
    return max;
  }
});
console.log(ans);
