title: Why are some websites' HTML and JavaScript so unreadable?
body: <p>I was trying to figure out what was going on in Facebook's login page and viewed the source in my browser. Some of the code is so unreadable it almost looks like somebody was just typing randomly:</p>
  
  <pre><code>&lt;script&gt;
  function envFlush(a){
      function b(c){for(var d in a)c[d]=a[d];}
      if(window.requireLazy){window.requireLazy(['Env'],b);}
      else{window.Env=window.Env||{};b(window.Env);}
  }
  envFlush({
      "ajaxpipe_token":"AXjTsqcPXwT0nKMR",
      "lhsh":"8AQEln95N",
      "khsh":"0`sj`e`rm`s-0fdu^gshdoer-0gc^eurf-3gc^eurf;
      1;
      enbtldou;
      fduDmdldourCxO`ld-2YLMIuuqSdptdru;qsnunuxqd;
      rdoe-0unjdojnx-0unjdojnx0-0gdubi^rdbsduOdv-0`sj`e`r-0q`xm`r-0StoRbs`qhof"
  });
  &lt;/script&gt;
  </code></pre>
  
  <p>Why is the HTML and JavaScript of most major websites so horrible and hard to read?</p>
