On minecraft, if you go to the End on creative mode, can you get back?

Just kill yourself by failing in the void(the darkness) you should respawn back to your bed

You can either defeat the Ender Dragon and a portal will spawn, or you can jump into the void, as suggested by Abdou. If you have cheats enabled, you can also type /kill me, and that should kill you instantly, and you should respawn at either your bed or the regular world's spawn.

I did not think you could die on creative mode.
