this question has answer here: which equals operator (== vs ===) should used in javascript comparisons? 48 answers what's reason use === instead of == typeof in javascript? 5 answers say wanted function checked whether or not variable string, interwebs advised me follows: function is_string(s) { return typeof s === 'string'; } but can't think of scenario "typeof s" return "string" without s being string. is there reason === operator instead of ==? reason being, want check types in switch statement, afaik, switch statement uses loose comparison operator. since i'm looking known types , don't need check undefined, should fine, right?
