title: How to break out from foreach loop in javascript
body: <p>I am newbie in Javascrript. I have a variable having following details:</p>
  
  <pre><code>var result = false;
  [{"a": "1","b": null},{"a": "2","b": 5}].forEach(function(call){
      console.log(call);
      var a = call['a'];
      var b = call['b'];
      if(a == null || b == null){
          result = false
          break;
      }
  });
  </code></pre>
  
  <p>I want to break the loop if there is NULL value for a key. How can I do it?</p>
