any() Function


any( predicate, list, context )

Calls a rule or function that returns either true or false for each item in list by asking the question, "Do any items in this list yield true for this rule/function?" with the intent to discover if any item(s) yield true.


Keyword Type Description


Function, Rule, or Data Type Constructor

Expression that returns a Boolean (true or false).


Any Type Array

List of elements that the predicate iterates through.


Any Type Array

Variable number of parameters passed directly into each predicate evaluation.



Usage considerations

Referencing expressions and rules

Use fn!functionName to reference an expression function and rule!ruleName to reference a rule.

Understanding results

Returns true as soon as the returned value of an evaluation yields true; otherwise, returns false.

Empty and null lists yield false.

Limitations and alternatives

Serves as an alternative to or(apply(rule!iseven, {-1,0,1,2})).

a!forEach() cannot be used within rules used in this function.


Given a function f(x) , any(fn!f, {a, b, c}, v)) returns or({f(a, v), f(b, v), f(c, v)})

any(rule!iseven,{-1,0,1,2}) returns true
