    Yo,

    This method won’t work anymore, “split” is depreciated, you need to replace with “explode” instead.

    Only trouble i am having is now that i use explode, it displays the filename followed by the extension, not just the extension on its own.

Posting Code

We highly encourage you to post problematic HTML/CSS/JavaScript over on CodePen and include the link in your post. It's much easier to see, understand, and help with when you do that.

Markdown is supported, so you can write inline code like `<div>this</div>` or multiline blocks of code in triple backtick fences like this:

```
<script>
  function example() {
    element.innerHTML = "<div>code</div>";
  }
</script>
```

We have a pretty good* newsletter.
