📄️ What is Functional Programming
Functional programming is a programming paradigm, a style of building the structure and elements of computer programs that treats computation as the evaluation of mathematical functions and avoids changing-state and mutable data. It is a declarative type of programming style. Its main focus is on "what to solve" in contrast to an imperative style where the main focus is "how to solve". It uses expressions instead of statements. An expression is evaluated to produce a value whereas a statement is executed to assign variables.
📄️ Immutable data and Pure functions
In Kotlin, we have a unique feature called immutable data. Immutable data, as the name suggests, cannot be modified once it's created. This means you cannot change the value of a variable after declaring it. This feature is an essential part of functional programming, as it helps to avoid side effects and makes your code safer and easier to reason about.
📄️ Higher Order Functions and Lambdas
In Kotlin, one of the key concepts you'll encounter is functional programming. This paradigm enables you to write cleaner, more efficient code. In this tutorial, we'll dive into the world of higher-order functions and lambdas, two powerful tools that are central to functional programming in Kotlin.
📄️ Closures and Inline Functions
Kotlin is a statically typed programming language that fully supports functional programming. In this article, we will discuss two key concepts in Kotlin's functional programming: closures and inline functions. Whether you're a beginner or an intermediate programmer, getting a good grasp of these concepts is essential to become proficient in Kotlin development.
📄️ Collections and Stream Operations
Functional programming is a coding paradigm that treats computation as the evaluation of mathematical functions and avoids changing state and mutable data. In functional programming, functions are first-class citizens. This means they can be passed as arguments to other functions, returned as values from other functions, or assigned to variables. Kotlin, as a statically typed programming language, supports this functional style of programming.
