##Usage
|
||
|
|
|
||
|
|
`sliced` accepts the same arguments as `Array#slice` so you can easily swap it out.
|
||
|
|
|
||
|
|
```js
|
||
|
|
function zing () {
|
||
|
|
var slow = [].slice.call(arguments, 1, 8);
|
||
|
|
var args = slice(arguments, 1, 8);
|
||
|
|
|
||
|
|
var slow = Array.prototype.slice.call(arguments);
|
||
|
|
var args = slice(arguments);
|
||
|
|
// etc
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## install
|
||
|
|
|
||
|
|
npm install sliced
