Ramda Compose With Promise

Added typings to composeWithPromise

  it('should await and return a composed result', async function() {
    const paramToProp = (param: string) => ({ param });
    const sleepingSentence = (s: number) => async ({ param }: { param: string }) => {
      const d1 = new Date();
      await sleep(s, TimeUnit.second);
      const d2 = new Date();
      return `a_[${param}], slept for: ${d2.getTime() - d1.getTime()}`;
    };
    const toUp = async (param: string) => param.toUpperCase();
    const removeStart = async (param: string) => param.slice(1);
    const composed = composeWithPromise(
      removeStart,
      sleepingSentence(1),
      paramToProp,
      toUp,
      sleepingSentence(2),
      paramToProp
    );
    return expect(composed('hey')).to.eventually.match(/_\[A_\[HEY\], SLEPT FOR: \d{4}\], slept for: \d{3,4}$/g);
  });
