#either

Returns a predicate that checks if a value satisfies either predicate.

Binary OR combinator — shorthand for anyPass([f, g]). When both inputs are type guards, the result narrows to the union of their target types.

const isNilOrEmpty = either(isNil, (s: string) => s === '')
isNilOrEmpty(null)

#Usage

#either<T>(f: (value: T) => boolean, g: (value: T) => boolean)

Returns a predicate that checks if a value satisfies either predicate.

Binary OR combinator — shorthand for anyPass([f, g]). When both inputs are type guards, the result narrows to the union of their target types.

#Parameters

#Returns

a predicate that returns true when either predicate passes.
