There is no third element involved, thereby making the functional program as pure as possible. For example, if you put in 2+2 in a calculator, the answer would always be 4. Pure functions follow the mathematics approach. The information available publicly points out such features being built for functional programming with Scala too. While most functional programming languages have similar advantages when it comes to the use of pure functions, Haskell, in particular, makes a clear demarcation between pure and impure functions. Because of this aspect of pure functions, algorithms developed using functional programming are easier to debug. Pure functions always produce the same output and have no external values affecting the end result. Furthermore, we would be able to understand why Mark Zuckerberg – one of the best minds in the industry – choose functional programming as the foundation for the most-used online platform. A discussion in this regard would help developers make better choices when choosing a language and optimize their approach. In this blog, we present an outline of some of the most significant advantages of functional programming over the likes of Object-Oriented Programming (OOP), among others. Haskell is used by Facebook, while WhatsApp uses Erlang. There are several functional programming languages, and some of the most important ones include Scala, Common Lisp, Haskell, and Erlang.
