When I saw the title, I thought this is about a native editor. A noble pursuit. As I read on I realized this is about a web based editor. Almost just as noble but I would not wish anyone go down this rabbit hole. You cannot build a good, performant and useful editor without sinking tons of work, as proved by many people. You could create something simple but will very quickly discover all sorts of problems and edge cases with it.
