Build, test, and debug regular expressions
Matches strings enclosed in single quotes, double quotes, or backticks, using a backreference (\1) so the closing delimiter always matches the opening one. The greedy dot-star (.*) captures everything up to the last quote on the line, and adding the s flag extends matching across newlines for multiline strings. Useful for extracting quoted text, string literals, or template literals in code parsing and data extraction tasks.
