DOM Methods
While the W3C pages are good the JavaScript Methods page is found under the JavaScript section while the Events are found under HTML DOM section. (I am not sure what I mean here?)
There are far too many Methods for me to document and I have no intention of trying! I only look into Methods as I find them in code that I am using.
The W3C page says
Some of the Methods I am using on this website
The createTextNode and appendChild Methods are used on my page to display HTML source on a iPad
The addEventListener method along with the classList Property are used in the Accordian technique (although I think that some of my pages using it are wrong)
