prefer-unknown-over-any

What problem does it solve?

Apply unknown instead of any when values have an unknown type, such as data from JSON, external sources, or untrusted inputs, reducing runtime errors and improving type safety.

Core Features & Use Cases

• Use unknown to force narrowing before use, preventing unsafe operations on values with unknown type.
• Encourage safer APIs by returning unknown until the value is validated.
• Apply in real-world scenarios like JSON parsing, external API responses, and user input handling to ensure safe usage.

Quick Start

Replace any with unknown when you don't know a value's type, then validate before use.
