 ### Fibonacci array generator
 
 Create an empty array of the specific length, initializing the first two values (`0` and `1`).
-Use `reduce()` to add values into the array, using the sum of the last two values, except for the first two.
+Use `Array.reduce()` to add values into the array, using the sum of the last two values, except for the first two.

-const fibonacci = n => {

-    .fill(0)
-    .reduce((acc, val, i) => {
