title: Read value or return
body: <p>Often writing function's code I need to make sure certain values are defined or I want immediately return false value. But writing whole <em>if</em> block feels too much typing. Is it possible to write instead of:</p>
  
  <pre><code>function getSomethingByModel(model) {
      var id = model.id;
  
      if (! id) {
          return;
      }
  
      // rest of the code
  }
  </code></pre>
  
  <p>Something like this:</p>
  
  <pre><code>function getSomethingByModel(model) {
      var id = model.id || return;
      // rest of the code
  }
  </code></pre>
  
  <p>This is pure aesthetics question, not functional one.</p>
