Finden Sie die zweitgrößte Zahl aus einem Array mit JavaScript

const array = [32, 523, 5632, 920, 6000];

let largestNum = array[0];
let secondLargestNum = 0;

for(let i = 1; i < array.length; i++) {
	if(array[i] > largestNum) {
    secondLargestNum = largestNum;
    largestNum = array[i];  
    }
  if else (array[i] !== largestNum && array[i] > secondLargestNum) {
  secondLargestNum = array[i];
  }
};
console.log("Largest Number in the array is " + largestNum);
console.log("Second Largest Number in the array is " + secondLargestNum);

/* Explanation: 
1) Initialize the largestNum as index of arr[0] element
2) Start traversing the array from array[1],
   a) If the current element in array say arr[i] is greater
      than largestNum. Then update largestNum and secondLargestNum as,
      secondLargestNum = largestNum
      largestNum = arr[i]
   b) If the current element is in between largestNum and secondLargestNum,
      then update secondLargestNum to store the value of current variable as
      secondLargestNum = arr[i]
3) Return the value stored in secondLargestNum.
