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.
