Summary

In this chapter, you learned about the best practices for clean and maintainable coding. As you saw in this chapter's activity, the refactored code that used clean coding techniques resulted in code that was much longer than before. However, you can see that the code as-is is much cleaner and is easier to understand and test compared to the original.

It is arguably overkill to refactor to the degree that we presented for our simple application, and many developers feel this way. But the value of this programming style really shows itself more in a complex real-world application, and it is good practice to do work in this way. Developers and tech leads need to decide what standards and clean coding practices make sense for their particular project.

In the next chapter, you will explore the current trends and cutting-edge features that JavaScript has to offer.
