javascript - Else statement not working -


i trying return longest word in array using foreach loop , return "00" when there no word. able part of returning longest word work correctly, when introduce else statement doesn't work anymore: 

function findlongestword(input) {   var arrwords = input.split(' ');   var wordlength = 0;   var word = '';   arrwords.foreach(function(wrd) {     if (wordlength < wrd.length && wrd.length % 2 == 0) {       wordlength = wrd.length;       word = wrd;     } else  {       return "00";     }   });   return word; }

your return "00" statement returns inner function , not findlongestword(input) function.

you can initialize word "00". return "00" if not set inside foreach.

function findlongestword(input) { var arrwords = input.split(' '); var wordlength = 0; var word = '00'; arrwords.foreach(function(wrd) {    if (wordlength < wrd.length && wrd.length % 2 == 0) {       wordlength = wrd.length;       word = wrd;    } }); return word; }
