You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: list_job_templates.go
    path of file: ./repos/golang-samples/media/transcoder
    
    the code of the file until where you have to start completion: // Copyright 2020 Google LLC

// you may n
    
func listJobTemplates(w io.Writer, projectID string, location string) error {
	// projectID := "my-project-id"
	// location := "us-central1"
	ctx := context.Background()
	client, err := transcoder.NewClient(ctx)
	if err != nil {
		return fmt.Errorf("NewClient: %w", err)
	}
	defer client.Close()

	req := &transcoderpb.ListJobTemplatesRequest{
		Parent: fmt.Sprintf("projects/%s/locations/%s", projectID, location),
	}

	it := client.ListJobTemplates(ctx, req)
	fmt.Fprintln(w, "Job templates:")
	for {
		response, err := it.Next()
		if err == iterator.Done {
			break
		}
		if err != nil {
			return fmt.Errorf("ListJobTemplates: %w", err)
		}
		fmt.Fprintln(w, response.GetName())
	}

	return nil
