title: lazy loading and $ocLazyLoad
body: <p>I recently discovered the <a href="https://oclazyload.readme.io/docs/getting-started" rel="nofollow">$ocLazyLoad</a> third party angular module which enables lazy loading of javascript files. I'm a bit confused about this concept. How is lazy loading different than caching, and why would you want to lazy load when using angularjs?</p>
