satisfies-exactly

any →
satisfies-exactly(
    count: integer,
    ...predicates: predicate
) → boolean

Returns true when exactly the requested number of supplied predicates are satisfied by the input. The count must be non-negative, and evaluation stops as soon as the result is known.

Parameters

Name	Type	Required	Description
count	integer	Yes	Specifies the exact non-negative number of predicates that must be satisfied.
predicates	predicate	Variadic (zero or more)	Specifies the predicate expressions evaluated against the same input value, in declaration order.

Argument evaluation

• count: Evaluated once against the incoming value to determine the required predicate count.
• predicates: Predicates use the same incoming value and are evaluated in declaration order. Evaluation stops as soon as the result is known.
