title: Removing elements from array where first letter matches character
body: <p>This is an angular 1 app.
  I have an array that looks like this:</p>
  
  <pre><code>var my_arr = [
      {key: 'KEY1', label: 'label1'},
      {key: 'KEY2', label: 'label2'},
      {key: 'KEY3', label: '#label3'}
  ];
  </code></pre>
  
  <p>I need to remove the items where the label begins with hashtag.
  Is there a way to do this with one liner? Or at least without manually looping the array?</p>
  
  <p>*****EDIT*****</p>
  
  <p>Basically, I need (in the example above) remove the item labelled "#label3" as it begins with hashtag (#).</p>
