Syntax

Classic signature

function whenHasInformationOtherwise<
  GenericInput,
  GenericInformation,
  GenericOutput,
  GenericOtherwiseOutput
>(
  input: GenericInput,
  information: GenericInformation | GenericInformation[],
  theFunction: (value: UnwrappedMatchingInput) => GenericOutput,
  otherwiseFunction: (value: Exclude<RawInput, MatchingInput>) => GenericOtherwiseOutput
): GenericOutput | GenericOtherwiseOutput;

Curried signature

function whenHasInformationOtherwise<
  GenericInput,
  GenericInformation,
  GenericOutput,
  GenericOtherwiseOutput
>(
  information: GenericInformation | GenericInformation[],
  theFunction: (value: UnwrappedMatchingInput) => GenericOutput,
  otherwiseFunction: (value: Exclude<RawInput, MatchingInput>) => GenericOtherwiseOutput
): (input: GenericInput) => GenericOutput | GenericOtherwiseOutput;

Parameters

• information: Literal information or array of informations to match.
• theFunction: Callback receiving the unwrapped matching payload.
• otherwiseFunction: Callback receiving the original raw non-matching input.
• input: Value processed immediately, or later with the curried form.

Return value

Returns the result of the matching callback when the condition succeeds; otherwise, it returns the result of otherwiseFunction. The otherwise callback always receives the original raw input.
