title: What is the difference between \Validator::make($input, $rules) and Validator::make($input, $rules)?
body: <p>It seems like that the <strong>Validator::make($input, $rules)</strong> is not working when I try to validate the request. The added prefix of <strong>"\"</strong> makes the job done.</p>
  
  <p>What is the reason behind this mark use since lots of the documentation and lectures don't make use of it?</p>
