🔍 Regex Match Operator

The =~ operator returns the index of the first match or nil. It also populates the global Regexp.last_match, making it a powerful tool for pattern matching.

text = "Order number: 12345"
if text =~ /(\d+)/
  puts "Found number: #{Regexp.last_match(1)}"
end
# => "Found number: 12345"
