const array = new Array(3).fill(0)
Here is what the above code is Doing:
1. We create a new array with 3 elements, all of which are 0.
2. We then use the fill() method to change all of the elements to 1.
3. We then use the map() method to multiply each element by 2.
4. We then use the filter() method to remove any element that is less than 3.
5. We then use the reduce() method to add all of the remaining elements together.
