Bug

On Windows npm start from cmd or powershell will only compile the full app (ie: either YesterTech or ProjectPlanner) to localhost:3000.

Expected result:

It compiles the chosen exercise/lecture to localhost:3000

Note: Installing WSL on Windows is suggested in Readme.md

Environment:

Windows 10 with latest updates. Either latest Chrome or latest Edge browser. Latest node.js LTS with latest npm.

Note: I do not have WSL[2] installed as suggested in the Readme.md

Steps to reproduce:

1. open powershell on windows in project directory
2. enter command npm start
3. make choices in terminal that lead to webpack compile of an exercise
4. navigate to localhost:3000 in web browser

or: enter npm start core-v1 1 and enter 1 for 'exercise'
or: enter npm start core-v2 1 and enter 1 for 'exercise'

Thanks for all this, I just haven't had a second to test it out yet. I hope to this week

Found an issue: this PR so far doesn't properly override files other than index.tsx. I have a change coming shortly that fixes that and just need a bit more time to push.
