Get all substrings inside a string that match a regular expression
javascript, regex
Solution
Use `match` to find all substrings that match the regex.
> "cats and rats".match(/(c|r)ats/g)
> ["cats", "rats"]
Now you can use `indexOf` and `length` to find the start/end indices.
Problem
Possible Duplicate: How can I match multiple occurrences with a regex in JavaScript similar to PHP's preg_match_all()? In Javascript, is it possible to find the starting and ending indices of all substrings within a string that match a regular expression? Function signature: ``` function getMatches(theString, theRegex){ //return the starting and ending indices of match of theRegex inside theString //a 2D array should be returned } ``` For example: ``` getMatches("cats and rats", /(c|r)ats/); ``` should return the array `[[0, 3], [9, 12]]`, which represents the starting and ending indices of "cats" and "rats" within the string.
