title: Load external modules (third party libs) in Angularjs
body: <p>Until recently I used to develop my js applications with Backbone-js.</p>
  
  <p>Now, I wish to start using Angular-js for the first time.</p>
  
  <p>In my backbone-js apps I used requirejs to load any third party library, it let my app stay organized and clean.</p>
  
  <p>Now, when playing around with angular, I see that in many examples they use <code>&lt;script&gt;</code> to load these modules.</p>
  
  <p>Is there a clean way to load modules without using this <code>&lt;script&gt;</code> tag? and keep angular functioning as expected?
  Is it common to use require-js for angularjs apps? or is there any alternative?</p>
  
  <p>Thanks.</p>
