In this post I'm going to show you a way of separating your concerns when it comes to dealing with the network communication of your application. First, lets start with a simple diagram. Data Mapper is an architectural pattern for separating the business logic of your domain model from the network communication logic. A Data Mapper is a Data Access Layer that performs bidirectional transfer of data between a persistent data store (often a relational database) and an in memory data representation (the domain layer).

In this series of articles we are going to go deeply into functional programming language concepts using the Javascript programming language. What is Functional Programming Functional Programming is not something new. We can track functional programming back to the 1930s with the introduction of Lambda Calculus by Alonzo Church, far before there was any computer programming language at all. You can read more about lambda calculus here. So what exactly is functional programming?
