Build, test, and debug regular expressions
Matches individual frame lines from V8 JavaScript stack traces (Chrome, Node.js), such as 'at myFunction (/app.js:10:15)' or 'at /app.js:10:15'. It handles the 'at ' prefix, an optional function name with opening parenthesis, and a location in file:line:column form or a non-parenthesized fallback, plus an optional closing paren. Useful for parsing error stack traces in logging, crash reporting, and log aggregation tools.
