Methods

findRangesWithRegex

The findRangesWithRegex method is a function that takes a text and a regular expression as input and returns an array of number ranges. It uses the exec method of the regular expression to find matches in the text, and for each match, it adds a range to the ranges array. The range consists of the starting index and the ending index of the match in the text. The method continues to find matches until no more matches are found. Finally, it returns the ranges array.
