can anyone explain if secondLargest ([2, 3, 44, 5, 44, 3, 7, 8, 11]) in the arr the optimised code will give 44 as second largest During the fifth iteration, the value of arr[i] is 44, which is equal to the current value of largest. Therefore, the else if condition is true, and the value of secLar is updated to the current value of largest, which is 44. The value of largest remains 44. During the sixth iteration, the value of arr[i] is 3, which is smaller than largest. The else if condition is also false, so nothing happens. During the seventh iteration, the value of arr[i] is 7, which is smaller than largest. The else if condition is also false, so nothing happens. During the eighth iteration, the value of arr[i] is 8, which is smaller than largest. The else if condition is also false, so nothing happens. In the ninth iteration, the largest value is 44 (which was updated during the eighth iteration), and the current value of arr[i] is 11, which is smaller than both the current largest and second-largest values. Therefore, there are no updates made to the values of largest or secLar during this iteration.

This isn't correct. What if you had array of the following: [4,7,6,5,2 1]. The second largest would be 6, but this code would return 4. That's why the second if statement is needed. In his first if statement however, he should've set secondLargest before updating the largest though because doing it the way he did it will cause both variables to store the dame value.

you have wrongly understood the problem in the if else(arr[i] !== firstlargest ) which means in the third index the 44 is overwritten by the immediate value of an array and those the immediate value we will compare with the arr[i] thats the reason we provided else if(arr[i] !==firstlargest ) i think you forget to enter "!" operator in the edge case statement
