body: <p>We know that <a href="https://stackoverflow.com/questions/3001836/how-does-java-handle-integer-underflows-and-overflows-and-how-would-you-check-fo">Java does not handle underflows and overflows</a>, but how does Javascript handle these for integers?</p>
  
  <p>Does it go back to a minimum/maximum? If yes, which minimum/maximum?</p>
  
  <p>I need to split a string and compute a hash value based on its characters.</p>
