The code below outputs the following by console.log:

bfe 2 3 dev

Explanation:

• The first console.log statement logs the four arguments passed to the log() function: 1, 2, 3 and undefined (as the fourth argument was not passed).
• The second console.log statement logs the modified values of the arguments using the "arguments" object. The first argument is changed from 1 to "bfe" and the fourth argument is changed from undefined to "dev", while the second and third arguments remain the same.
