Re^2: Remove empty element.

Or grep away null elements. I admit that I do this sometimes simply to save cognitive load as opposed to CPU load.

my @array = ('',1,2,'',3,'',4);
@array = grep { $_ } @array;
print join "}{",@array;
print "\n";

gives

1}{2}{3}{4

`@array = grep { $_ } @array;` This `grep` also removes array elements that happen to be `0`. Use `grep { defined && length }` instead if you want to have the `0` elements in the result.

Good catch - in this case there aren't any, but you're still right. :)	[reply]
