title: When to use a virtual list?
body: <p>I'm building a feed like Facebook or Twitter using React. I need a list of posts... however, I don't know if it's worth having a virtual list or not.</p>
  <p>I don't know the height of each post until it's been rendered as it might contain an image or a video, I also need the whole window to scroll (not just one element), and I need it to be an infinite list (to load more posts when the users reaches the bottom).</p>
  <p>What benefits would I get from using a virtual list rather than simply displaying all posts? it seems like a lot of work to maintain and set up what I'm looking for.</p>
