### pullAll
|
||||||
|
|
||||||
|
Mutates the original array to filter out the values specified (accepts an array of values).
|
||||||
|
|
||||||
|
Use `Array.filter()` and `Array.includes()` to pull out the values that are not needed.
|
||||||
|
Use `Array.length = 0` to mutate the passed in array by resetting it's length to zero and `Array.push()` to re-populate it with only the pulled values.
|
||||||
|
|
||||||
|
```js
|
||||||
|
const pullAll = (arr, pullArr) => {
|
||||||
|
let pulled = arr.filter((v, i) => !pullArr.includes(v));
|
||||||
|
arr.length = 0; pulled.forEach(v => arr.push(v));
|
||||||
|
}
|
||||||
|
// let myArray = ['a', 'b', 'c', 'a', 'b', 'c'];
|
||||||
|
// pullAll(myArray, ['a', 'c']);
|
||||||
|
// console.log(myArray) -> [ 'b', 'b' ]
|
||||||
|
```
