+### Pull
+
+Use `Array.filter()` 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.
+Use `Array.push()` to re-populate the original array to equal the pulled values
+
+```js
+const pull = (arr, ...args) => {
+  let pulled = arr.filter((v, i) => args.indexOf(v) === -1);
+  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' ]
+
+// let test = ['4', '1', '1', '5', '4', '2'];
+// pull(test, '4', '1');
+// console.log(myArray) -> [ '5', '2' ]
+```
