In this chapter, we have built ourselves a great foundation, exploring the very fundamentals that underpin all of the code we write. We have discussed how our code is an expression of intent, and how, in order to build that intent, we must have a sound understanding of what the user requires and the problem domain we are engaging in. We have also explored how we can write code that is clear and readable to humans, and how we can create clear abstractions that provide users with the ability to leverage complexity.
In the next chapter, we will build on this foundation with the specific tenets of clean code: reliability, efficiency, maintainability, and usability. These tenets will be lending us a vital perspective as we go on to study the many facets of JavaScript and how we can wield it in the service of clean code.
