title: Is it sometimes necessary to use multiple javascript libraries?
body: <p>I'm new to web development and don't fully understand the role a js framework plays in an app. I've started with jQuery, but people have said I should try prototype.js or node.js for my project, which is a multiplayer strategy game. </p>
  
  <p>Is it important to select a framework early on, and making sure it does everything you need so you don't have to use multiple frameworks?</p>
