title: jQuery: how to generate 3 different random integers given limits/range?
body: <p>I'm trying to generate 3 different random integers but I can't do that with jQuery, a little bit different in some ways comparing that with JS.</p>
  
  <p>For example, I have 20 different questions to make in my app, but I only want to see 5 different questions, all of them random.</p>
  
  <p>I look for it and I think I should use this function for that purpose:</p>
  
  <pre><code>$.randomBetween(minValue, maxValue);
  </code></pre>
  
  <p>but it only gives you one single number. How to get 3, between 1 and 20, being different each other?</p>
