title: What is the fastest/easiest headless-browser supporting Javascript?
body: <p>I'm doing a project on node.js using a Js framework to make a multiplayer game, but to run the logic of the game on the server, asking, they have told me that I must run it on a headless browser.</p>
  
  <p>The problem is that today is the first time I hear about them, I have searched information on Google and it appears that the fastest is zombie.js, but it hasn't many info about how it works and my programming skills are limited.</p>
  
  <p>So I ask, what is between the headless browsers which support Javascript and are fast, the easiest to use, I would just need to simulate the game on the browser and capture the position of the players on it and maybe the speed(depending how it works), nothing else.</p>
