Max-Min

Question: Write a program to find the min/max element of an array.

Method 1
//Using inbuilt functions

const arr = [20, -3, -15, -20, 3, 15, 40];

function minMax(arr) {
   const min=Math.min(...arr);
   const max=Math.max(...arr);
   return [min, max]
}

console.log(minMax(arr));
//Prints: [-20, 40]
Method 2
//Without using inbuilt functions

const arr = [20, -3, -15, -20, 3, 15, 40];

function minMax(arr) {
  let min=arr[0], max=arr[0];
  for (let i = 1; i < arr.length; i++) {
    let value = arr[i];
    min = (value < min) ? value : min;
    max = (value > max) ? value : max;
  }
  return [min, max];
}

console.log(minMax(arr)); 
//Prints: [-20, 40]
