What will the output be in the console for the following code: const months = ['Jan', 'March', 'April', 'June']; months.splice(3, 1, 'May'); console.log(months);?

In the provided code, the splice method is executed on the months array. This method is used to add or remove elements from an array. The syntax of the splice method is array.splice(start, deleteCount, item1, item2, ...), where start is the index at which to start changing the array, deleteCount is the number of elements to remove, and (item1, item2, ...) are the elements to add to the array starting at the start index.

In this case, the code executes months.splice(3, 1, 'May'). The start index is 3, which corresponds to the fourth item in the array (since indexing begins at 0). The second argument, 1, indicates that one element should be removed at that index. The third argument, 'May', specifies that this element will be added at the same index where the removal occurs.

Initially, the array is ['Jan', 'March', 'April', 'June']. At index 3, the value is 'June'. The splice method removes 'June' and adds 'May' in its place. As
