JS Currying example

 const responseGoogleStatus = (responseType) => {
    return (response) => {
      console.log(responseType, response);
      if (responseType == "Success") {
        loggedIn = true;
        token = response.accessToken;
      }
      if (responseType == "Failed") {
        throw new Exception("Some error from Google API response", response);
      }
    };
  };
  
  //Then call the currying function to get a function back with 'responsType' (in this case) already 'filled in'
  const successFn = responseGoogleStatus("Success")
  const failureFn = responseGoogleStatus("Failed") 
  
  //Finally use successFn and failureFn as a callbacks for an API Promise for example
