From 512418731a95b2db7554cd230f5f328b02d9dbe8 Mon Sep 17 00:00:00 2001 From: Carlos Diaz Date: Thu, 13 Apr 2023 12:30:22 -0700 Subject: [PATCH] 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. --- 04_removeFromArray/README.md | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/04_removeFromArray/README.md b/04_removeFromArray/README.md index d3a2ee9..4d1da13 100644 --- a/04_removeFromArray/README.md +++ b/04_removeFromArray/README.md @@ -10,7 +10,7 @@ removeFromArray([1, 2, 3, 4], 3); // should remove 3 and return [1,2,4] 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. - 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).
