body: <p>I am trying to discern the difference between </p>
  
  <pre><code>if 
  else 
  else if 
  </code></pre>
  
  <p>When do you use them and when not?</p>
  
  <p>I have a homework assignment with a ton of instances and I am running into code error due to not knowing the differences between each.</p>
  
  <p>Can someone please define how to use these?</p>
