Nintendo switch controller

[Diy2019]

Looking to buy a Nintendo switch online and don't understand the controllers.
When you buy the console is there only one controller in the box?
If so, then can i buy the plug in controller or do I need the joy con controller? Will either work? Just confused as there's such a big price difference between them.

The Nintendo Switch has a joy con controller on each side and can be used as a one player controller or two smaller, individual controllers.

You won't need to buy anything extra

Mine all use pro controllers, they are teens though I wouldn't buy them for younger kids

Is it the normal Switch or the switch lite? On the switch light the joy cons (controllers) can't be removed

I've just bought an extra controller for two player games as the single controllers were just too small but I get thumb pain from an old injury.
