title: JavaScript: mouseenter event in JavaScript?
body: <p>Is there a mouse enter event in javascript(only JavaScript, no jQuery to be used, please)?</p>
  
  <p>When I do this, it gives no response.</p>
  
  <pre><code>window.onload = initAll;
  function initAll(){
      if(window.addEventListener){
          document.getElementById('container').addEventListener( 'mouseenter', freeze , false);
      }
  }
  
  function freeze(){
      console.log("mouse entered")    
  }
  </code></pre>
  
  <p>Could someone Please explain me the difference between 'mouseenter' and 'mouseover'? Is 'mouseover' an alternative for 'mouseenter'?</p>
  
  <p>Help Appreciated!</p>
