# Array Week Challenge - Day 3

Heyyyyyy! It's the start of a work week but we're already 3 days into our challenge week. Let's do this!

### ⏰ You can Catch Up in no time!

We're on day 3 of this week's challenges which build upon each other. 

Feel free to catch up: 
- [Day 1](https://blog.barbaralaw.me/huntober-2022-day-8) 
- [Day 2](https://blog.barbaralaw.me/huntober-2022-day-9)

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 3

** 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. **

Today's challenge is a bit of a tangent, but I think it's pretty powerful. It's inspired by my favorite [Codewars](https://www.codewars.com) kata ever, [Moving Zeros To The End](https://www.codewars.com/kata/52597aa56021e91c93000cb0/javascript). This is my favorite kata because the first time I did it, my approach was so convoluted compared to the top-voted solution, which was a thing of beautiful simplicity. I think the moment I saw that solution something clicked for me and I realized the power of the built-in Javascript methods.

Today I'd like you to **write a function that**:
- **takes in a given array of strings and move any entries containing the letter 'a' to the front** 
- **then move any remaining entries that have over 3 characters to the back**
- **please preserve the relative order of entries within their given category**

Example:

```
myArr = ['hi', 'hello', 'howdy', 'hola', 'hej', 'hallo', 'heyyy']
// move things around
=> ['hola', 'hallo', 'hi', 'hej', 'hello', 'howdy', 'heyyy']
```

Have fun!

#### *Wait, What's Huntober?*

*[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.*
