In this chapter, we have tried to explore the challenge of effective communication in a technical context, and have broadly discussed the communicative process involved in taking a problem from the ideation stage to the prototype stage. We have also covered the task of communicating and advocating for technological change, whether in the form of bug reports or raising broader issues concerning systemic problems. Programmers are not just the authors of code; they operate as part of the systems they are building, as crucial agents in the iterative feedback cycles that result in clean software. Understanding the considerable roles we play in these systems and feedback cycles is hugely empowering and begins to get to the crux of what it means to be a clean JavaScript programmer.

In the next and final chapter, we will be bringing together everything we have learned in the book so far, exploring a new problem domain via a case study. That'll conclude our exploration into clean code in JavaScript.
