ryans words

js

var readline = "The rain in Spain falls mainly on the plain.";

## L should be downcase

var LongestWord = function(sen) {
    var words = sen.split(" ");
    var longest = 0;
  for (i = 0; i <= words.length; i++) {
    if (longest.length < words[i].length) {
      longest = words[i];
    }
  }
  return longest; 
         
}
## should be  print(LongestWord(readline));    ##readline is variable not function
print(LongestWord(readline()));   

Manual Loop Type !!!
    i    words[i]  longest
1.  0     'the'      0
Already broke because we call longest.length on line 9, the length of 0 doesn't help us here


So lets change it:

var readline = "The rain in Spain falls mainly on the plain.";
var longestWord = function(sen) {
    var words = sen.split(" ");
    var longest = 0;
  for (var i = 0; i < words.length; i++) { ###the var was missing here
      console.log(words[i])
    if (longest < words[i].length) { 
      longest = words[i].length; ## now we are ocmparing the longest number to the length of the current word. 
      word = words[i] 
    }
  }
  return word; 
         
}
   

print(longestWord(readline));
