Three Common Categories of Functions
In the preceding chapters, we have looked at some of the core components of functional programming. We have discussed how to write functions that adhere to both functional programming and pure functional programming.
In this chapter, we are going to look at some practical implementations of functions that leverage these concepts. These are the categories and topics we will cover:
- The first category we will look at is predicate-based functions
- Then, we will take a look at data transformation functions, which maintain the structure of our data (more on that later)
- Finally, we will take a look at functions, which transform the data and reduce the information into a single value
This is not meant to be an exhaustive list, but with these three categories, we can build a large portion of our day-to-day applications.
