Function mapKeys

mapKeys<TType extends any[] | any[][], TReturn = string>(
    chainOrChord: TType,
    func?: (
        key: TType extends any[][]
            ? TType<TType>[number][number]
            : TType[number],
    ) => TReturn,
): TType extends any[][] ? TReturn[][] : TReturn[]
Map keys of a chain or chord* by the given function.

Useful for inspecting a chain/chord when debugging.

*This is determined by checking if the first element is an array or not.
Type Parameters
- TType extends any[] | any[][]
- TReturn = string
Parameters

          : TType[number],
  ) => TReturn = ...
Returns TType extends any[][] ? TReturn[][] : TReturn[]
