Hello world!

Ultimately, learning functional programming will make you a better programmer. Functional programming is a form of declarative programming . Instead, think of it as another programming technique that will open up your mind just as OOP, templates, assembly language, etc may have completely changed your way of thinking when (if) you learned them. In this blog piece, I explain why it has made sense for me to study FP and why you should also learn it. It avoid concepts of shared state, mutable data observed in Object Oriented Programming. My two cents with respect to functional programming is to not get hung up on a particular language, but learn the key concepts of functional programming. But it ought not to be. Microsoft introduced FP support with the release of .NET 3.5. Do not think of functional programming in terms of a "need". Another good way to learn Haskell is to do so while following Erik Meijer’s MOOC on functional programming on edX, which you can follow along in Haskell or one of several other languages. It's hard learning functional programming on your own. I know what you’re thinking. Functional langauges empazies on expressions and declarations rather than execution of statements. Functional programming (also called FP) is a way of thinking about software construction by creating pure functions. Functional programming is a declarative paradigm because it relies on expressions and declarations rather than statements . The concepts are abstract, yes. Functional programming is a style that emphasizes immutable data, functional primitives, and avoidance of state. But that doesn't make them incomprehensible. What is Functional Programming? Data Structures and Functional Programming Spring 2020 Why Learn About Functional Programming? Following the FP philosophy entails foregoing things like shared states, mutable data and side effects. Functional Programming (FP) in simple words is a "Declarative Programming". If the inclusions of functional programming principles in Python and other languages are of any significance, however, then functional programming seems to be gaining traction. Functional programming (FP) is a programming paradigm for developing software using functions. In order to make the most of this, I suggest choosing the language with the most different perspective: Haskell. That makes perfect sense: functional programming is great for big databases, parallel programming, and machine learning. You wrote some Lisp in college and dreaded it. You will learn a lot just by working in a language with so much history. It shouldn't be this difficult. The functional programming paradigm was explicitly created to support a pure functional approach to problem solving. My studying of Functional Programming has profoundly influenced me, and this data-centric approach arises from this studying and learning. Functional programming is one of the first paradigms (invented around the time of procedural) and has fed the other paradigms ideas and features since its inception, including the if statement. This is the first in a four-part series on things I wish someone had explained to me about functional programming. You don't need a PhD to understand functional programming. Even if you never end up using functional programming, learning it teaches you new ways to think. That means FP does not deal with how to do (lines of code for achieving some functionality) but speaks about what to do. A course on functional programming at Cornell University. I learned functional programming by being tossed headfirst into a project in which my boss insisted all development be done in APL.
