Thank you. This clarified a lot of things.
Noticed a few issues working through this...
First, the setup npx command seems to be "webpack-typescript", not typescript-webpack.
Flipping it causes an error.
In addition, the virtualenv command also seemed to break on my Windows environment. There was some "setuptools" issue.
What worked was
python -m venv edtwExampleEnv
Moving the Part 2 issues to Part 2.
