+## [Remove All The Marked Elements of a List](https://www.codewars.com/kata/563089b9b7be03472d00002b/train/javascript)
+
+##### Story
+
+- Define a method/function that removes from a given array of integers all the values contained in a second array.
+
+#### Examples (input -> output):
+
+```js
+* [1, 1, 2, 3, 1, 2, 3, 4], [1, 3] -> [2, 2, 4]
+* [1, 1, 2, 3, 1, 2, 3, 4, 4, 3, 5, 6, 7, 2, 8], [1, 3, 4, 2] -> [5, 6, 7, 8]
+* [8, 2, 7, 2, 3, 4, 6, 5, 4, 4, 1, 2, 3], [2, 4, 3] -> [8, 7, 6, 5, 1]
+```
+
+##### Notes
+
+- If no button is currently active, return Nothing.
+- If the list is empty, return Nothing.
+
+#### Solution:
+
+```js
+Array.prototype.remove_ = function(integer_list, values_list){
+  return integer_list.filter(item => !values_list.includes(item));
+}
+
+// Usage
+console.log(removeValues([1, 1, 2, 3, 1, 2, 3, 4], [1, 3])); // [2, 2, 4]
+console.log(removeValues([1, 1, 2, 3, 1, 2, 3, 4, 4, 3, 5, 6, 7, 2, 8], [1, 3, 4, 2])); // [5, 6, 7, 8]
+console.log(removeValues([8, 2, 7, 2, 3, 4, 6, 5, 4, 4, 1, 2, 3], [2, 4, 3])); // [8, 7, 6, 5, 1]
+```
