Tutorials should have links to the relevant Reference pages

[davej]

I was noticing that it is sometimes not so easy to find the relevant reference page. You search, you find the tutorial, so then you look at the tutorial, but it leaves out some details, so then you need to find the reference page. For example, this page; http://www.w3schools.com/js/js_popup.asp Should include these three links; http://www.w3schools.com/jsref/met_win_alert.asphttp://www.w3schools.com/jsref/met_win_confirm.asphttp://www.w3schools.com/jsref/met_win_prompt.asp
