It turns electricity into heat.
The toaster is a device that toasts, but toasting was done long before the invention of the electric toaster. Toasting on an open fire is undoubtedly the earliest method, which predates the electric toaster by countless thousands of years.

a toaster caramelizes the surface of the bread. this is the very earliest stage of charing, before any actual char forms.
