It is opposite to the imperative paradigm where the sequence of statements can update the running state of the program. It is a declarative programming paradigm where function definitions are trees of expression that map values to other values. Taking this definition to next level, functional programming involves writing code in pure functions. Generally, a paradigm is a way or a model or you can say, a pattern solving a particular problem in computer science. What Is A Functional Programming Language?įunctional programming is a programming paradigm. Also, here in this blog post, we will be talking about the top 16 functional programming languages that are popular and used by developers worldwide. Let’s move further with the introduction to functional programming. Things are changing and at present, Every developer seems excited to learn it, use it, and leverage it to create modern, secure, and useful products in less time. Yes, functional programming has been around for the last 60 years but it is more like a ‘known yet unknown’ thing to the development world. Why are we talking about this? Have you heard the term ‘Functional Programming’? You might say it’s in trend these days. Trends can change the entire software development world in just a few days.
