Creates a new array with `n` elements removed from the left.
|
|
|
|
- Use `Array.prototype.slice()` to remove the specified number of elements from the left.
|
|
|
|
```js
|
|
const drop = (arr, n = 1) => arr.slice(n);
|
|
```
|
|
|
|
```js
|
|
drop([1, 2, 3]); // [2, 3]
|
|
drop([1, 2, 3], 2); // [3]
|
|
drop([1, 2, 3], 42); // []
|
|
```
