### 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.
|
|
|
|
```js
|
|
var fibonacci = n =>
|
|
Array.apply(null, [0,1].concat(Array(n-2))).reduce(
|
|
(acc, val, i) => {
|
|
acc.push( i>1 ? acc[i-1]+acc[i-2] : val);
|
|
return acc;
|
|
},[]);
|
|
```
