+### Array pull (mutates array)
+
+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 pull = (arr, ...args) => {
+  let pulled = arr.filter((v, i) => args.includes(v));
+  arr.length = 0; pulled.forEach(v => arr.push(v));
+};
+// let myArray = ['a', 'b', 'c', 'a', 'b', 'c'];
+// pull(myArray, 'a', 'c');
+// console.log(myArray) -> [ 'b', 'b' ]
+```
