My purpose in writing Gnoga is so you don't have to know it :)

However, http://www.w3schools.com/ is a nice resource even though I've found many mistakes and omissions it is well and good enough for most of what is needed.

As time permits in the big picture I'll write some internal documentation as well. I have notes of important issues to discuss there.

One point about internals that you should understand (although it may take some time first depending on your knowledge of HTML5 and JS so far to get this) is that Gnoga creates objects _outside_ the Document's DOM and inserts them in later using the Element.Place_* methods or by way of views that use those methods internally. Gnoga assigns each new object to a place in the gnoga object on the page itself for internal reference. This is not the case for "attached" DOM objects that are only in the DOM and referenced by their DOM_ID (from Gnoga.Types.ID_Enumeration) always. So if they are removed from the DOM unless assigned to a JS variable and the ID_Type switche to Script they will be "lost".

The other point is that Gnoga (for the most part) to place a compatibility layer across browsers uses jQuery on the browser side and not directly JS DOM functions. This could easily be changed in a few lines of code and perhaps at some point I may.
