Redesign your JavaScript file so that extra consecutive whitespaces are not counted.

Tip: The variable sum should increase if the inserted character is not the white space

Solution:

var myTextareaElement = document.getElementById("myWordsToCount");
myTextareaElement.onkeyup = function(){
  var i=0;
   sum=0;
   var myValue = document.getElementById("myWordsToCount").value;
   var res = myValue.split(" ");
   while (i<res.length) {
     /* The variable sum increases if the inserted character is not the white space*/ 
     if (res[i] != "") {
         sum=sum+1;
     }
   i=i+1;
 }
 document.getElementById("wordcount").innerHTML = sum;
 console.log(res, i, res.length);
