Created Oct 9, 2017
An example of Recursion. A factorial function is defined as: factorial of n is n times the factorial of n - 1, except for factorial of 0 which is 1. Therefore, we can write this as:
View factorialFunction.js
| function factorial(number) { | |
| if (number === 0) { return 1; } | |
| return number * factorial(number - 1); | |
| } | |
| // factorial(0) -> 1 | |
| // factorial(1) -> 1 | |
| // factorial(2) -> 2 | |
| // factorial(3) -> 6 | |
| // factorial(4) -> 24 |
