# Array Week Challenge - Day 2

Hello, hello! Here we are on the second day of our second week of Huntober daily challenges!

### ⏰ Need to Catch Up?

Did you miss yesterday's challenge? Each day builds on the last towards a final solution on Friday of each week. Check out this week's [challenge for Day 1](https://blog.barbaralaw.me/huntober-2022-day-8) and then head back over here.

I've also added all of this month's challenges to a series here on my blog - hope that helps!

## ⭐ Array Week

This week our challenges all deal with Arrays! Their purpose is to store a collection of things under a single reference name, but the way they are set up and used in JavaScript is a little different from other programming languages. If you're coming from a different language, be sure to check out what's different! While working on our challenges, feel free to use JavaScript's built-in [Array methods](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array#instance_methods).

## 🏆 The Challenge - Day 2

** This week we'll be working with arrays toward a final puzzling result on Friday when we combine our daily functions. Your solutions should be built to work within any given daily constraints. **

So it turns out that some of the information I stored ever-so-safely in arrays just isn't looking right. I'm not going to be happy until it feels right, you know what I mean? Could you help me rearrange things a bit?

I need **twin functions, a function that swaps a given primitive value in a given 1-dimensional array to an index to the left, and another that swaps it to the right**. 

Some things to note:
- If the given value is on the edge of the array and can't move in that direction, don't move it. 
- The given primitive value will only occur once in the array
- The array passed in should be mutated by this function. *Scandalous, I know*.

Example:
```
myArray = ['abc', 'xyz', 1, 2, 'Hey!']

// call move left function with 'xyz' and myArray as arguments
console.log(myArray)   // ['xyz', 'abc', 1, 2, 'Hey!']

// call move left function again, same arguments
// Note that 'xyz' is already as far left as it can go
console.log(myArray) // ['xyz', 'abc', 1, 2, 'Hey!'] no change

// call move right function this time, with 2 and myArray as arguments
console.log(myArray) // ['xyz', 'abc', 1, 'Hey!', 2]

// call move right function again, same arguments
// Note that 2 is already as far right as it can go
console.log(myArray) // ['xyz', 'abc', 1, 'Hey!', 2] no change

```

Got it? Great! I can't wait to get moving things around.

*[Leon Noel's 100Devs](https://leonnoel.com/100devs/) are spending October preparing for the job hunt. Anyone who has already broken into a tech career knows that the application and interview process can be grueling! The current cohort has progressed this year all the way from basic HTML files to hosted full-stack applications with authentication and databases.*


*This month they'll continue to build, but will also work on data structures & algorithms, networking and interview skills, and solving code challenges.*
