Gets the first `n` elements of an array.
|
|
|
|
- Use `Array.prototype.slice()` with a start value of `0` and an end value of `n` to get the first `n` elements of `arr`.
|
|
|
|
```js
|
|
const firstN = (arr, n) => arr.slice(0, n);
|
|
```
|
|
|
|
```js
|
|
firstN(['a', 'b', 'c', 'd'], 2); // ['a', 'b']
|
|
```
