I would like to know what's the best way to create, edit and show element. Should i create three pages : showElementView.html, editElementView.html and createElementView.html with three differents controllers showElementController.js, editElementController.js and createElementController.js
or
create one page ElementView.html and one controller ElementController.js with and a variable mode that allow me to detect in which mode i am.
Do you have w3c standard, best web practices or something else that explain this to me.
