Summary

In this chapter, we integrated knowledge from previous chapters to revisit pipelines and composition. We started with function composition, showing how to combine simple functions into complex operations using higher-order functions for mapping and filtering collections.

We then introduced the Pipe method, which simplifies a pipeline’s function chaining. When applied to our book publishing system example, it enabled clear processing steps for querying, validating, transforming, and submitting a manuscript.

Then, we examined the fluent interface pattern, which allows quite intuitive method chaining. The ManuscriptProcessor class demonstrated how a fluent interface can make our code more expressive and user-friendly. We also covered advanced composition with monads using the Result type for graceful error handling in monadic pipelines.

The next chapter will be the last of our journey, and I truly hope you enjoy the process. So, finish the exercises if you haven...
