B.10. Lists and Arrays
Perl has a number of
features that make it easy to manipulate an entire list or array.
B.10.1. map and grep
We mentioned (in Chapter 17, "Some Advanced Perl Techniques") the
map
and grep
list-processing operators. They can do more than we could include
here; see the perlfunc manpage for more
information and examples.
B.10.2. The splice Operator
With the splice
operator, you can add items to the middle
of an array, or remove them, letting the array grow or shrink as
needed. (Roughly, this is like what substr lets
you do with strings.) This effectively eliminates the need for linked
lists in Perl. See the
perlfunc manpage.
