/*
  Description:
  Write a script that creates an array with 10000 random words between 3 and 5 characters, and returns the number of words that are palindromes in that array;
  Notes:

      The code needs to be in javascript
      You’ll need to return just the number of words
      You have 30 mins, if you run out of time, submit the form anyway.
      Once you click “Start” you cannot pause the countdown
      Don’t delete the main function
      
      const main = () => { 
      
      }
