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

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

• A. ["Jan", "March", "April", "June"]
• B. ["Jan", "March", "April", "May"]
• C. ["March", "April", "May"]
• D. ["Jan", "May", "April", "June"]

Answer: (B)

The output of the code will be `["Jan", "March", "April", "May"]` due to the behavior of the `splice` method in JavaScript. In this code snippet, the `months` array initially contains four string elements: 'Jan', 'March', 'April', and 'June'. The `splice` method is called with three arguments: it starts at index 3 (which corresponds to 'June'), removes 1 element from that index, and inserts 'May' in its place. The `splice` method modifies the original array directly and returns an array containing the deleted elements. Since we specified to remove one element starting at index 3, 'June' is removed, and 'May' is added to the array at that index. Thus, the modified array becomes `["Jan", "March", "April", "May"]`. This is why the console will output the modified array, reflecting the change made by the `splice` method.
