Remove All The Marked Elements of a List

Story

• Define a method/function that removes from a given array of integers all the values contained in a second array.

Examples (input -> output):

* [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:

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]
