title: How to sum two different functions in javascript
body: <p>I have different functions which return values; So i created different function to sum both values.</p>
  
  <pre><code>function result(){
      var result = firstFunct() + secondFunct();
      alert(result);
      return result;
  }
  </code></pre>
  
  <p>And it gives for me a result like joint of two strings: 1010 instead 20. What kind of operator do I need to use two sum both of them?</p>
