Summary

In this, the final chapter, we have explored a real-world problem through the lens of the principles and learnings that we have gathered throughout the book. We posed a problem that users were encountering and then designed and implemented a user experience that solved their problem in a clean way. This included both server-side and client-side pieces, enabling us to see, from start to finish, what a self-contained JavaScript project may look like. Although we haven't been able to cover every single detail, I hope that this chapter has been helpful in cementing the core ideas behind clean code and that you now feel better prepared to write clean JavaScript code to tackle all types of problem domains. One core tenet I hope you can take away with you is simply this: focus on the user.
