var str = "The quick brown fox jumped over the box like an ox with a sox in its mouth";

str.match(/\w(ox)/g); // ["fox", "box", "sox"]

// match (when used with a 'g' flag) returns an Array with all matches found
// if you don't use the 'g' flag then it acts the same as the 'exec' method.

str.match(/\w(ox)/); // ["fox", "ox"]
/\w(ox)/.exec(str);  // ["fox", "ox"]
