Depends where in the array you want to cut stuff out and if you're rmoving a single element at a time or multiple elements... splice
is the most general (i think any shift
can be re-written as a splice
), whereas shift
only remove a single element, and only from the very front or back (respectively) of the array.
perldoc -f splice
perldoc -f shift
perldoc -f pop
so, to summarize:
if only one element from front, then shift
else if only one element from back, then pop
(Note also there are probablly different ways besides splice
as well -- e.g. could probably rewrite using map/grep/array slices)
