It is considered good practice to only `throw` the `Error` object itself or an object using the `Error` object as base objects for user-defined exceptions.
The fundamental benefit of `Error` objects is that they automatically keep track of where they were built and originated.

This rule restricts what can be thrown as an exception.

:::warning
This rule is being renamed to [`only-throw-error`](./only-throw-error.mdx).
When it was first created, it only prevented literals from being thrown (hence the name), but it has now been expanded to only allow expressions which have a possibility of being an `Error` object.
With the `allowThrowingAny` and `allowThrowingUnknown` options, it can be configured to only allow throwing values which are guaranteed to be an instance of `Error`.

The current name `no-throw-literal` will be removed in a future major version of typescript-eslint.
