When to use AngularJS? : <p>I want to develop a website by my own. I want to make different web applications which need to interact with databases. I read about AngularJS, a JavaScript framework. The thing I do not understand is: When to use AngularJS? Do I first build my website in HTML &amp; CSS and then add functionality to it with AngularJS? How do professional developers start with that?</p>

<p>Thanks.</p>
