User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:53.0) Gecko/20100101 Firefox/53.0 Build ID: 20170504105526 Steps to reproduce: ctrl-shift-i console "1234,123,12".match(/12/) Actual results: Array [ "12" ] returned an array with the search string in the element. Expected results: Array [ "1234,123,12" ] I would have suspected, if grep is any indicator of how regex matching is to be done, it returns the line found that matches. is this according to spec?

String.prototype.match returns the matched substring. If you need to the complete string, the regexp needs to be changed to `/12.*/`.
