=over =item push ARRAY,LIST X X Adds one or more items to the B of an array. my @animals = ("cat"); push(@animals, "mouse"); # ("cat", "mouse") my @colors = ("red"); push(@colors, ("blue", "green")); # ("red", "blue", "green") Returns the number of elements in the array following the completed L|/push ARRAY,LIST>. my $color_count = push(@colors, ("yellow", "purple")); say "There are $color_count colors in the updated array"; Starting with Perl 5.14, an experimental feature allowed L|/push ARRAY,LIST> to take a scalar expression. This experiment has been deemed unsuccessful, and was removed as of Perl 5.24. =back
