If you buy a physical Switch title, is it region-locked? [duplicate]

Many Nintendo devices often come with regional locking, which means if you purchase a device in one country, you won't be able to play games from another (generally).

Is the Nintendo Switch also region locked like many of its predecessors such as the Wii U and Wii?

The Nintendo Switch is region-free. As the link states:

Nintendo president Tatsumi Kimishima confirmed the system won’t be region locked, meaning players will be able to play globally released software on the console-handheld hybrid.

The Wikipedia page for the Switch explains further:

Unlike previous Nintendo home consoles, the Switch is region-free. This allows players to use cartridges or downloaded content from any part of the world, with the exception of Chinese game content which can only be played on Switch units manufactured for that country. Nintendo recommends using the appropriate regional eShop for digital purposes for obtaining the best post-purchase support if needed.
