Reports throwing values that are not Error objects.
✅ This rule is included in the ts logical presets.
Only Error objects (or objects that extend Error) should be thrown.
Throwing non-Error values has several downsides:
- No stack trace information for debugging
- Inconsistent error handling behavior
- Cannot use standard error properties like
cause, message, or name
This rule reports on any throw statement where the value being thrown is not an Error.

This rule is not configurable.
If you’re working with legacy code that throws non-Error values and refactoring would be too costly, you may disable this rule.
