[removed] find longest word in a string

Question

function longestWord(string) {
    var str = string.split(\" \");
    var longest = 0;
    var word = null;
    for (var i = 0; i < str.length - 1; i++) {
                


        

Answer 1

ForEach is faster in FF but slower in Chrome, but for loop with the cached length and function apply/call is quite faster in both FF and chrome.

Hope the below code helps:

function getLongest (arrStr) {
  var longest = 0, word;

  for(var i=0 , len = arrStr.length ; i < len ; i++){

    if(longest < arrStr[i].length) {
       longest = arrStr[i].length;
       word = arrStr[i];
    }

  }

  return word;
}

function isLongest (str) {
  var arrayStr = str.split(' ');
  return function(fn) {
    return fn.apply(this,[arrayStr]);
  }
}

isLongest("hello aaaaaaaaaaaaaaaaaaaaaaaaa bbb")(getLongest); //aaaaaaaaaaaaaaaaaaaaaaaaa
