In this chapter, we gained an appreciation of some of the most prevalent enemies of clean code. We discussed how JavaScript itself is a language that, when wielded incorrectly, can invite unclean code. We also explored the pitfalls of both teams and the individual. We learned that clean code is not merely a characteristic of code but a culture that must be fostered both throughout an organization and within our own minds.

In the next chapter, we will explore some well-known and some less well-known principles of clean code and integrate what we've learned so far into some concrete JavaScript abstractions.
