There is a ... "movement", if you will, to promote better JS documentation
. I have seen this banner on sites such as thechangelog.com.
So far I have no recollection of receiving wrong information from w3schools. But they have also never been my only source of information. For ze Germans there is the superb and unmatched SELFHTML
, which seems a little outdated:
SELFHTML: Version 8.1.2 vom 01.03.2007
Selfhtml has examples for virtually everything, and it's all hyperlinked. For many this is the one-stop reference work.
I tend to use w3schools less and less these days for two reasons: bad press from many opensource sites that employ the banner you see above; and because I do less and less web stuff (and I feel great about it!)
