Problems with the following: step property, webkit property, c.stop, c.fadeOut

[LaurenWallace]

The image below contains all I know about the four problems from what the browser tells me. When I researched the first one, someone said that jQuery Slim removes some functions required by jQuery UI and that a full version of jQuery needs to be utilized. When researching the second problem it seems to be a jQuery version issue. The last two I am not sure about as it deals with lines 16 and 17 in the code.

Any help you could provide in fixing these issues would be fantastic. And thank you for posting this Chat Room example I find I have a better understanding of how I would use Node.js, and the other modules to do this.
