title: Does this code mean 'not equal'?
body: <p>I just want to know if <code>(clickedNumber === 'Yes or No')</code> means if the clickedNumber = 'Yes or No', then if I want to say the clickedNumber doesn't equal  'Yes or No', then is it like this:</p>
  
  <p><code>(clickedNumber !== 'Yes or No')</code>?</p>
  
  <p>Thanks</p>
