Remove elements of a Perl array

Question

Is there an easy way to remove n consecutive elements of a Perl array (thus making it shorter in length)?

Answer 1

You are looking for the Perl builtin function splice, which lets you pick a starting point, number of elements to remove, and an optional replacement list.

my @array = 0 .. 9;

my @slice = splice @array, 3, 3;

say "@slice";   # prints "3 4 5"
say "@array";   # prints "0 1 2 6 7 8 9"
say 0 + @array; # prints 7

Answer 2

You can use splice to remove array elements.
