# Array Week Challenge - Day 1

Hey everybody! Welcome to the first day of my second week of daily web dev challenges this October 🎃. 

These challenges are designed to be a bit of fun mixed with a bit of coding practice. Beginning each Saturday, the daily tasks will build towards discovering a final solution the following Friday. If that sounds like something you want in on, welcome!

### ⭐ Here's how it works

- Each week will have a cumulative goal
- Each day I'll write a post with the challenge of the day
- Check my [Huntober Twitter](https://twitter.com/huntoberTweets) for updates (and possible hints)
- **Save your code and solution from day to day!** The challenges are cumulative
- Please don't spoil it for everyone and share your answers without spoiler warnings
- I'll share my approach and solutions each week
- Have fun and maybe even learn some tricks!

## ⭐ 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 1

** 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. **

Do you know how to compare arrays? Not sure? Don't worry, you'll figure it out...

Today's task is to **write a function that will check equality between 2 arrays with a particular structure**. 

The arrays will:
- Be of equal size
- Will each contain some number (X) arrays
- Each inner array will contain that same number (X) primitive elements

**All the nested primitives within each array must strictly match to return a `true` result. Any mismatches will return `false`.**

For example:

```
// each of these arrays have 3 nested arrays of 3 strings each 
const arr1 = [['a','b','c'],['d','e','f'],['g','h','i']]

const arr2 = [['a','b','c'],['d','e','f'],['g','h','i']]
const arr3 = [['a','B','c'],['d','E','f'],['g','H','i']]
const arr4 = [['a','b','c'],['g','h','i'],['d','e','f']]

// if we were to use our function to compare all the possible pairs
// ONLY arr1 vs arr2 would return true

checkEquality(arr1, arr2) => true
checkEquality(arr1, arr3) => false
checkEquality(arr1, arr4) => false
// etc.
```

Good luck! Check back tomorrow for the next challenge of the week!

*[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.*
