Scala Functional Programming Patterns

---

Before we start learning Scala, let's first understand what functional programming (FP) is. You may have used a spreadsheet while working. In a spreadsheet, there is a bunch of equations and we enter values in the given cells for these equations. We get the answers through these equations. When you enter the same values again, you get the same answer and there are no fallouts. At the core of FP is composition. Looking at a software system made up of parts, we build bigger parts by composing smaller parts. If you think about it, most complex systems are composed of parts, which in turn are composed of smaller parts. Functional languages give us the means to make this composition. One of the prominent functional languages that can be used for FP is Scala. Scala in Italian means a staircase. If you look at the language's logo, you will see it's a staircase. The language acts as a staircase through which we can ascend and become better at programming. Scala also refers to the very many techniques that we can use to control the complexity of large-scale systems.
