const { createAlchemyWeb3 } = require("@alch/alchemy-web3");

If this is the "Completed" versions. Then it should be complete and ready to run (except maybe api keys).
The fact that

hello-world-part-four-tutorial/completed/package.json

Line 5 in a93cbbf

"dependencies": {

does not include @alch/alchemy-web3 makes this folder not a complete version of the project.

Please fix.
You are tying to use this to teach newcomers. They can not learn if you do not provide complete examples. They can not be expected to find and fix such problems on their own.

Thank you
