title: Which is faster: making your own database "lib" or using a third party lib
body: <p>So I'm actually on a project that connects an IRC bot to a game server. And I needed to store the username, the player's stats, and ban expiration(if the user is banned). I'm fairly new to node.js and don't know much about node js databases,so I kind of made my own,using JSON. The JSON file is like that:  </p>
  
  <pre><code>    {
    "Player": [
      {
        "name": "LucasTT",
        "stats": [
          103,
          1
        ],
        "banExpires": 0
      },...
  </code></pre>
  
  <p>And I made my own functions to access the database and didin't find it hard. So,is it better to use a lib like CouchDB or make my own(as I kind of did)?(Performance wise and how hard it would be to setup).</p>
