title: javascript remove string before a specific character
body: <p>I've been looking and looking but can only find variations of the question I have...</p>
  
  <p>I'm needing to remove a string before a character (including the character, and the spaces before and after the character). The string will be different each time and unpredictable, so no matter what it is it needs to be removed from the DOM. So, if this is the output:</p>
  
  <pre><code>&lt;h2&gt;Birds - Norwegian Yellow Finch&lt;/h2&gt;
  &lt;h2&gt;Cats - Domestic Shorthaired Tabby&lt;/h2&gt;
  &lt;h2&gt;Dogs - Alaskan Husky Cross&lt;/h2&gt;
  </code></pre>
  
  <p>How do I remove "Birds - , Cats - , Dogs - "? And without being specific about those words (Birds, Cats, Dogs) because those will change. The dash (-) can be a different character, if needed (ie: *).</p>
