In this section, we'll learn a few more advanced features that handlebars has to offer. This will make it easier to render our markup, especially markup that's used in multiple places, and it will make it easier to inject dynamic data into your web pages.
In order to illustrate the first thing we'll talk about, I want to open up both about.hbs and home.hbs, and you'll notice down at the bottom that they both have the exact same footer code as follows:
<footer>
<p>Copyright {{currentYear}}</p>
</footer>
We have a little copyright message for both and they both have the same header area, which is the h1 tag.
Now this really isn't a problem because we have two pages, but as you add more and more pages it's going to become a real pain to update your header and your footer. You'll have to go into every file...
