tsentials/predicate

You can combine type guards by creating individual predicates and composing them using logical operators like `and`, `or`, and `not`. This builds reusable validation rules that maintain consistent type narrowing across complex domain filtering conditions.

The best way to maintain consistent boolean conditions across sync and async flows is to define composable predicates once and reuse them. This prevents scattering ad-hoc boolean checks and ensures validation logic remains standardized throughout your application.

To narrow unknown values safely, use predicate refinements that act as type guards. By applying `refinement` and intersection narrowing with `andRefinement`, you ensure values are safely validated and their types are narrowed for subsequent operations.

Yes, you can convert a predicate into a rule-compatible function using `Predicate.toRule`. This standardizes validation-style flows by transforming your composable boolean conditions into a format that rule engines can process directly.

Use `Predicate.all` when every condition in a bulk composition must match, acting as a logical AND. Use `Predicate.any` when only one condition needs to match, acting as a logical OR, allowing you to create complex rules efficiently.
