Build, test, and debug regular expressions
Matches monetary amounts with a dollar sign either before or after the number, such as '$1,299.50' or '99$'. The captured numeric portion may include digits, decimal points, commas, whitespace, and 'k' or 'd' suffixes (e.g., '$10k'). With global and case-insensitive flags, it is ideal for extracting all price values from multiline text regardless of format variation.
