Utilities and utility types.

Result<T, E>

Result type: Success | Failure

const someResult = (): Result<string, string> => {
  Math.random() > 0.5 ? success("some value") : failure("some error");

  console.log(result.value);
} else {
  console.log(result.error);
}

const joinStringToInt = pipe(join, parseInt);
const val = joinStringToInt("1", "2", "3"); // -> 123
