regex-findall.js

/* Inspired by Python's useful re.findall method */

function findall(regex, str) {
	var matches = [], m;
	regex.lastIndex = 0;
	while (m = regex.exec(str, regex.lastIndex)) {
		matches[matches.length] = m;
	}
	return matches;
}

/* Example usage:

var matches = findall(/\d+/, '123 456 789');

*/

When I ran this in node and in Firefox I got stuck in an infinite loop beucase regex.lastIndex is always 0 - I think your function requires regex to be global so the example regex should be /\d+/g?

I think you can get the same result with '123 456 789'.match(/\d+/g)?
