MDN have a great explanation for that exact example.
Ken Alger W3 Schools is considered to be a bad reference as it's not updated and lacks newer information about today's standards, you can read more about this over at http://www.w3fools.com/.

10,554 PointsThanks for this guys. I didn't understand that the sort method is set up to take either a negative or positive value from a supplied compare function. Otherwise it reverts to it's default (sorting by string). So the coder needs to create a function that compares two numbers and which ever one is negative goes first.

26,676 PointsI think you're mistaking W3Schools which have no affiliation to the W3C or World Wide Web Consortium as they're known.
Also I find it somewhat unusual that you say you prefer less information as generally the more you have the easier it is to understand.
In any case I believe Hakan has plenty of information now :)

21,699 PointsI'm not mistaking, I'm talking about w3Schools. Nowadays most of their content is pretty ok, and its easier to understand in case you dont know much about documentation, besides the fact it uses a generally more simple vocabulary, even tough its not always 100% correct. ex on documentation is things like function (arg1, [context]) if you are not experienced, you dont really understand whats the brackets doing there

39,199 PointsIf you are looking for HTML & CSS references there are better choices than W3Schools. Also many newbies here on the forum aren't clear about the distinction between the W3C and W3Schools, so anytime you post a link to it it's best to clarify the lack of affiliation.
In terms of vanilla JavaScript there is no really great source I've found online.
