In this Article we will go through how to calculate the factorial of a number only using single line of code in JavaScript.
This is a one-line JavaScript code snippet that uses one of the most popular ES6 features => `Arrow Function`

Let's define this short function:

```
const factorial = n => n <= 1 ? 1 : n * factorial(n - 1);
```

```
factorial(2); // 2
factorial(3); // 6
factorial(4); // 24
factorial(5); // 120
factorial(6); // 720
```
