What are best practices for working with global matching /g?

When working with global matching in Perl using the `/g` modifier, it's essential to follow certain best practices to ensure efficient and effective pattern matching. Here are some tips:

• Always use regular expressions that are efficient and avoid excessive backtracking.
• Use the `/g` modifier when you expect multiple matches in a string.
• Store matches in an array to easily manage and manipulate them.
• Be careful with the position of your match variables, as they can overwrite previous results.
• Utilize non-capturing groups when you don’t need to save matched groups.

# Example of using global matching in Perl
my $text = "apple banana apple orange apple";
my @matches = ($text =~ /apple/g);  # Using global match

print "Found apple $matches[0] times.\n";  # Output: Found apple 3 times.
