    const argsArray = operatorList.argsArray;
    const fnArray = operatorList.fnArray;

    }
    const chunkOperations =
      argsArrayLen - i > EXECUTION_STEPS &&
      typeof continueCallback === "function";
    const endTime = chunkOperations ? Date.now() + EXECUTION_TIME : 0;

        stepper.breakIt(i, continueCallback);
        return i;
      }
      fnId = fnArray[i];
      if (fnId !== OPS.dependency) {
        this[fnId].apply(this, argsArray[i]);
