FIND THE LONGEST WORD IN A STRING

Challenge is to return the length of the longest word in the provided sentence.

Response should be a number.

It was tough one for me initially then i went through a post on git-hub describing what to do when you are struck up. I am putting the link here for reference.

  

How to start when you are stuck (I)

This is a three part series. A must read for all the new coder. My next step was to make a flow chart. but in part II of the series, the above mentioned challenge is discussed with flow chart along with pseudo-code. It helped me a a lot. With the help of this pseudo-code, I quickly came up the solution. 

My solution is given below

 function findLongestWord(str) {


     var arr = str.split(' '); 

     var max = 0; 


    for (var i = 0; i < arr.length; i++){

        var item = arr[i].length;

   

         if (item > max){

             max = item;

          }

  }  

   return max;   

}
