Concepts of functional programming
We can also distinguish functional programming from imperative programming by the concepts. The core ideas of functional programming are encapsulated in the constructs such as first class functions, higher order functions, purity, recursion over loops, and partial functions. We will discuss the concepts in this topic.
First-class and higher-order functions
In imperative programming, the given data is more important and are passed through series of functions (with side effects). Functions are special constructs with their own semantics. In effect, functions do not have the same place as variables and constants. Since a function cannot be passed as a parameter or returned as a result, they are regarded as second ...
