Array slice
Array slice allows you to retrieve multiple elements from array by specifying the index.
# Array slice my @values = @array[0, 3, 5];
This is an example to get the elements with indexes 1 and 3 from the array.
# Get multiple elements my @nums = ('a', 'b', 'c', 'd'); my @choice = @nums[1, 3];
The result is that if @nums is ('a', 'b', 'c', 'd') then @choice is ('b', 'd').
To slice an array against array reference, you can do the following:
# Array slice against array reference my $nums = ['a', 'b', 'c', 'd']; my @choice = @$nums[1, 3];
Use array slice as lvalue
Using an array slice as an lvalue allows you to assign to multiple values with a specified index.
# Use double array slice as lvalue my @nums = ('a', 'b', 'c', 'd'); @nums[1, 3] = ('e', 'f');
Hash slice
A similar feature to array slice is hash slice. You can get multiple values by specifying hash key.
