# 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:

- 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).  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).

Added jest Removed generator-exercises folder as it breaks jest-codemods run jest-codemods on .spec.js files, move generator-exercises back in Change references from Jasmine to Jest in main readme Update README with Jest specific language. Update some spec files with new syntax update tests, multiple exercises .gitignore: Added package-lock.json, package.json that were used when I ran code-blocks over the tests. Standardised function declaration calls across exercises fix typo in caesar.spec.js Ignoring package-lock.json, package.json Backtrack on .gitignore modification, add instructions to readme move files from testing repo to this repo Typo fixes, remove duplicate exercise folder Remove solution from non-solution branch Minor grammatical fixes added trailing semicolon to all function and module exports Fix words caught by search/replace action. remove doubled semicolon. Correct words caught by search/replace action. Add missing semicolon. Add .DS_Store to .gitignore multiple files: Added a blank line at the end of each file Ignore generator-exercise when linting exercise files Update exercise number of each exercise Update exercise number 2021-03-03 02:13:24 +00:00			`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:`

Adds additional hint. 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 19:28:33 +00:00			- 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.
