perl function next

The next keyword in Perl is used to skip to the next iteration of a loop. It is often used in conjunction with a conditional statement to skip certain iterations based on some criteria. Here's an example:

for my $i (1..10) {
  next if $i % 2 == 0;  # skip even numbers
  print "$i\n";
}

In this example, we use a for loop to iterate over the numbers from 1 to 10. Within the loop, we use the next keyword to skip any even numbers (i.e. those that have a remainder of 0 when divided by 2). The print function is then used to display each of the odd numbers.

The output of this program would be:

1
3
5
7
9

Note that the next keyword only skips to the next iteration of the loop; it does not exit the loop entirely. If you want to exit the loop based on some condition, you should use the last keyword instead.
