Review Comment:
should the terminating step be `to_list()`?
> Create Sample Applications in each GLV
> --------------------------------------
>
> Key: TINKERPOP-2995
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2995
> Project: TinkerPop
> Issue Type: Improvement
> Components: dotnet, go, javascript, python
> Affects Versions: 3.5.7
> Reporter: Yang Xia
> Priority: Major
>
> It would be great to have working example applications for each GLV, with
> basic traversal examples and common connection settings.
> Currently we have an `example.py` for python, but it is very minimal. There
> is also an `example.go` for golang, but that appears to be outdated. As far
> as I know, dotnet only has templates and javascript doesn't have any examples
> at all.
