Re: Creating an Intermediate Perl Programming Curriculum

# foreach vs. for

Err, and the fact that they are exactly the same, just easier to read, depending on context. For example, these just don't flow through the brain as comfortably:

foreach (my $i=0; $i<10; $i++) {
     print "$i\n";
}

for my $i (0..9) {
     print "$i\n";
}

But I know what you mean :)

Yes, that, and the ability to use `for` in a single statement like `if` and `unless`. For example: `s/foo/nofoo for @array;` [download]	[reply] [d/l] [select]

You can use `foreach` in the exact same manner. They are synonyms. One can always be used in place of the other: `$ perl -le 'print foreach 1, 2, 3' 1 2 3` [download]	[reply] [d/l] [select]
