The last section of this chapter is about assembling functions that realize larger behavior out of smaller functions. There are two ways to assemble such functions. The first is to use the appropriately named compose() function, which performs a nested invocation of the provided functions, or where order is important, we can use the flow() function to return values together.

Composing functions

The compose() function builds a new function out of the provided functions. When we call this new function, a nested ...
