### 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' ]
```
