Перепишите пример кода без блока try/catch.?

async function getData(){
  const a = await someFunction().catch((error)=>console.log(error));
  const b = await someOtherFunction().catch((error)=>console.log(error));
  if (a && b) console.log("some result")
}

async function loginController() {
  try {
    const a = await loginService().
    catch((error) => {
      throw new CustomErrorHandler({
        code: 101,
        message: "a failed",
        error: error
      })
    });
    const b = await someUtil().
    catch((error) => {
      throw new CustomErrorHandler({
        code: 102,
        message: "b failed",
        error: error
      })
    });
    //someoeeoe
    if (a && b) console.log("no one failed")
  } catch (error) {
    if (!(error instanceof CustomErrorHandler)) {
      console.log("gen error", error)
    }
  }
}
