perl sigils
# Basic syntax: # In Perl, variables generally start with one of $, @, or % (called sigils) # Scalars (strings, floats, ints) start with $, e.g.: my $scalar_variable = "This string"; # Arrays (lists) start with @ my @array_variable = (2.3, 42, "Word"); # Hashes (dictionaries) start with % and use "key => value" to assign mappings my %hash_variable = ( 42 => "The answer", mice => "vast, hyper-intelligent pan-dimensional beings", );
