title: What is the difference between yoyo and repeat in framer-motion
body: <p>I found out that yoyo and repeat are quite identical in framer-motion. I can't find any documentation on yoyo. Only repeat is documented.</p>
  <pre><code>transition:{{yoyo:3}}
  transition:{{repeat:3}}
  </code></pre>
  <p>Basically they do animation loop. I only notice the animation loop is slightly different in other details that I can't name.</p>
  <p>Can anyone show me the link to yoyo documentation or give me some ideas of their difference or similarity?</p>
