title: RequireJS: Difference between "requirejs" and "require" functions
body: <p>I am using requireJS 2.x. I found out that some tutorials (and the official docs) sometimes use </p>
  
  <pre><code>requirejs.config({ [...] });
  requirejs(["module"]) ...
  </code></pre>
  
  <p>and sometimes</p>
  
  <pre><code>require.config({ [...] });
  require(["module"]) ...
  </code></pre>
  
  <p>Is there any difference between those two functions (require and requirejs)? I could not find any word about that in the docs. :(</p>
