yeah, the Switch has a few security features, including their browser not supporting JIT compilation, which is how a lot of web exploits work. It's also running webkit, which is the same underlying browser that most phones and computers use.
Also, Nintendo also has on their end a kill-switch: if they find out something in the browser is exploitable, they can force disable it until the next system update. In homebrew circles, this message is called the super nag (displays when trying to launch the browser):

here's what PegaSwitch looks like when it activates (only works on older Switch firmwares):
