Confusing content on the Basic Plugin Creator page

[james-deee]

In the beta version found here:

https://github.com/jquery/learn.jquery.com/blob/master/page/plugins/basic-plugin-creation.md

The very first part has some confusing content about the use of "trim". Unfortunately, the example given and the conversation about trim don't match up.

Here's the example used:
$( "a" ).css( "color", "red" );

But then the paragraph below it says:
"Additionally the jQuery utility method $.trim() is used above to rem....."

I think you might have meant to have a different example case where you were using trim?

Thanks! PS. I LOVE the new content about plugin authoring.
