Find largest and smallest number in an array?

Steps:

• Assign first element of array to largest and smallest
• Iterate over the array
• If element is larger than largest, assign to largest
• If element is smaller than smallest, assign to smallest

function findLargestSmallestInArray(arr) {
    let largest = arr[0];
    let smallest = arr[0];

    for(let i = 0; i< arr.length; i++) {
        if (arr[i] > largest) {
            largest = arr[i];
        }
        if (arr[i] < smallest) {
            smallest = arr[i];
        }
    }

    return [largest, smallest];
}

findLargestSmallestInArray([20,14,592,57,2,4,50,1]);
