You should take JSLint's advice. ;^)
You're also welcome to take any code snippet I've sole-source posted on StackOverflow.com and consider it to be at worst dual-licensed under the MIT license as found at that URL on May 28, 2015 for you, and as a rights reserved copyrighted source when I use it in other projects.
For those snippets, if you want to attribute, that's great. Just know that you're using them at your own risk.
I'm now going to plug my favorite [personal] project, though [hopefully] far from my best code, SQLDbSharp, a YesSQL database engine pitifully kludged together using C#, and my quixotic quest to create a great mail client, MailMobius.
