+# Exercise 04 - removeFromArray
+
+Implement a function that takes an array and some other arguments then removes the other arguments from that array:
+
+```javascript
+removeFromArray([1, 2, 3, 4], 3); // should remove 3 and return [1,2,4]
+```
+
+## Hints
+
+The first test on this one is fairly easy, but there are a few things to think about(or google) here for the later tests:
+
+- how to remove a single element from an array
+- how to deal with multiple optional arguments in a javascript function
+- [Check this link](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/arguments).  Scroll down to the bit about `Array.from` or the spread operator. - [Or this link](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/rest_parameters).
