Carlos Diaz 512418731a Adds hint to exercise There's an idea I've been made aware of called undesirable difficulty in learning theory. The idea is that sometimes obstacles are put in place that take the focus off learning a specific thing by introducing a challenge on a thing that might be related but not critical to the task at hand. In this exercise, I notice pretty much everyone reaches for the splice method and I suspect it is because of the language in the prompt. Specifically: "removes the other arguments from that array" I've added a hint that I think would not take away from the challenge but give learners an alternative way to think about the exercise.		2023-04-13 12:30:22 -07:00

Exercise 04 - removeFromArray

Implement a function that takes an array and some other arguments then removes the other arguments from that array:

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:

throughout the logic in your removeFromArray function, you can manipulate the original array you pass into the function call or create a new array that is returned as the result.
