LOL .....w3fools.com is made by bunch of idiots.
Its been a subject of debate for quite a long time and most of the mistakes which they have pointed is already fixed by w3schools.com.
Those jerks were unable to do anything productive so they did something foolish and the same reflects in their name.
More importantly almost all the errors that were pinpointed by those morons are non-critical and are for
HTML/CSS/Javascript and not for SQL.
Please dont post misleading links.
w3schools.com is highly recommended and reputed site and many professional web devs recommend it personally .
I myself have learnt SQL/CSS/HTML from it and i am able to implement every piece of info from that site(w3schools.com) into my projects.
Since you have started it now i must finish it:
Jus quoting few notes from w3fool.com
www.w3schools.com/JS/js_obj_array.asp.
It lists new Array() as the way to create an array. The problem is that this is the old, slower way. The new way, [] is shorter and it makes you look cool.
Just check out the reasoning of these w3fool guys.

www.w3schools.com/html/html_colors.asp,
www.w3schools.com/html/html_colornames.asp,
www.w3schools.com/html/html_colorvalues.asp
This is all CSS stuff. It should not be listed in the HTML section. Additionally, the Color Names page lies: not all browsers support the 130 SVG colors.
No explanation needed.They have even resorted to do the honourable job of pointing the proper section for contents even when w3schools.com has clearly mentioned that the any offtopic refrences is for directional purposes and has been explained in their respective sections.
the whole damn page is filled wit trash like that.
