10. Interim Conclusion

Examples 01 through 28 have presented, one by one, all the concepts required by the case study:

The case study brings them all together into a complete, realistic-sized application (approximately 80 files and 6,400 lines, including comments). It was written with the same care as the examples: each file begins with a comment explaining its role, and tricky sections are annotated in the code. Each main folder also contains a file named [README.md] that lists its files. The document’s commentary highlights what the examples did not show and refers to them for the rest.
