what is the best place to learn and be a strong coder in javascript, jquery, php, ajax and json online... Apart from w3schools and tizag, different hype and bad comments about w3schools are every where online. All this tutorials have chanllenges that are giving to be solved on your own. This might not be all the tutorial web site you provide. Thank you and am waiting in anticipation.

Read ebooks.

For effective video tutorials on all of the above and much,much more check out http://thenewboston.org/tutorials.php and u won't regret it

@geraldcole, please provide some links to the ebooks, while i check some out in the programming section. @cmespeak, thanks for the link.

check out http://www.codecademy.com/#!/exercises/0 codecademy is the best i swear

w3schools.com u gonna lov it

w3schools and newboston are amazing platforms IMO.

The best website for webdesign tutorials ranges to their content.
To more i will say, the best is the one that meet my need at that point in time.
E.g: you might be looking for a way to solve a problem, and some website might have that solution so i will rate them best.
you site are good for reference, e.g. w3schools, tizag,webdesign.about.com, and many more.

thank you all for all your contribution

Ur best bet would be PDFs...and maybe videos from youtube(lectures)
