recursion

Introduction to Functional Programming Functional Programming (FP) is a programming paradigm that includes specific techniques. There are both purely functional programming languages like Haskell, Clojure, and Scala, as well as programming languages that support functional programming techniques, such as JavaScript, Python, and Ruby. While the concept of functional programming dates back to the 1930s with the birth of lambda calculus, it has gained significant momentum recently. This is the perfect time to learn about functional programming, especially through JavaScript examples....

In JavaScript, recursion refers to the ability of a function to call itself. This powerful concept allows us to solve problems in a clean and efficient way. To implement recursion, you need to use a named function expression. Let’s dive into its basics. Consider the simple example of calculating the factorial of a number. The factorial of a number is obtained by multiplying it with all the positive integers less than itself....
