I do own the book. Only the issue here is, strictly Jira-oriented programming. You only ever modify lines that fall into your ticket. You don't lint, don't remove trailing spaces, insert missing semicolons. You DO.NOT.CLEAN.UP. It's not enough to have IE-compatible code that follows naming conventions, README.md and .eslitrc (used very sparingly). You must use arbitrarily chosen existing functions, and on code review you're given very vague suggestions like "use the function we have for that", or "eh". Files commonly over 3000, 5000 lines.
