Bonus (Optional)

In Projects/2-Intermediate/Expense-Splitter.md around line 37, the compound
adjective "open-source inspired" is hyphenated incorrectly; change it to "open
source–inspired" (use "open source" as the noun phrase and an en dash or hyphen
between "source" and "inspired" per style) so the line reads: [Settle
Up](https://settleup.io/) – open source–inspired expense app.
