What is Firefox’s error console doing?

Can someone explain this to a person who knows nothing about coding?

Example:
“Warning: anonymous function does not always return a value
Source File: //www.makeuseof.com/answers/wp-includes/js/jquery/jquery.js?ver=1.3.2
Line: 19, Column: 198
Source Code:
if(K){F.push({elem:K,fn:J})}}});F.sort(function(J,I){return o.data(J.elem,”closest”)-o.data(I.elem,”closest”)});o.each(F,function(){if(this.fn.call(this.elem,H,this.fn.data)===false){return(G=false)}});return G}function i(F,E){return[“live”,F,E.replace(/\”

    Riley, are you still seeing the issue?

    It's trying to tell you that there might be some error on the Javascript of the makeuseof site, which, considering how many different plugins run here, is not a surprise at all. The questions is, if you don't know coding, why are you using error console? It's usually used by developers to clean their own code.

    There's broken Javascript jQuery code on the page.

    Without more information as to the page content, what's trying to be accomplished and whether or not the site is currently in development, there's not much more to say to a non-coder.
