title: What do big companies use to build up their dynamic html pages
body: <p>What do modern companies use to build up the actual html page using data.
  And what programming languages do they use to show the data in the html.
  If they use Java for example, do they use an engine to pass the data to the html, or do they just add the variable to the html as a string? (for example: <code>"&lt;p&gt;Hello" + name + "!&lt;/p&gt;"</code>).
  And how do they loop data in the html? Using just a for loop and adding it to an string? Or via an engine?</p>
  
  <p>In PHP it's simple, but what do they use in stead of PHP to generate the html?</p>
