β | {{w|Functional programming}} is a | + | {{w|Functional programming}} is a style of computer programming that uses only function calls, and not other traditional programming tools like loops. Functional programming often uses {{w|Recursion (computer science)|recursive functions}} to serve the same purpose that loops serve in other programming languages. A recursive function calls itself again, typically with slightly different arguments. E.g., the following {{w|Factorial|factorial function}} is recursive because it calls itself again for any argument value n greater than 0. |
