regex - What does the this javascript regular expression do?: "var match = self.location.href.replace(/\/$/i, '');" -


i saw expression in codebases library part of following sequence:

var url = sel.anchornode.parentnode.href; var match = self.location.href.replace(/\/$/i, ''); var replaced = url.replace(match,'');
