# String Week Challenge - Day 1

Hey all! Welcome to the first day of my first 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!

## ⭐ String Week

This week our challenges all deal with Strings! As one of JavaScript's primitive data structures, Strings are critical to understand and manipulate. Feel free to use JavaScript's built-in [String methods](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String#instance_methods).

## 🏆 The Challenge - Day 1

**This week we will be discovering hidden messages by manipulating a given string. Your solutions should account for any non-empty string. On Friday we'll combine our functions to decode a message.**

Oh no! How did this happen?! Somehow similar-looking numbers and letters have been confused in our document. Someone may have been messing around writing naughty words on a calculator. We need to get them back to normal. 

Below, find the mix-ups that have been made. Note: the confusion happened in **both directions** and was **case-sensitive**.

```
'0' <-> 'O'      '5' <-> 'S'
'1' <-> 'I'      '6' <-> 'G'
'2' <-> 'Z'      '7' <-> 'L'
'3' <-> 'E'      '8' <-> 'B'
'4' <-> 'h'      '9' <-> 'q'
```

As an example, here is how a string looks before and after the characters are fixed:

```
"PR0-T1P #hqB: 1T'5 N1C3 T0 5AY H3770." 
// implement fix function -> 
"PRO-TIP #498: IT'S NICE TO SAY HELLO."
```

**Please create a function that will fix a given string of this mistake before incalculable damage can be done!**

*If you want to get a head start on untangling this week's message, check out my [Huntober Twitter](https://twitter.com/huntoberTweets) account where I've shared the full input string already.*

#### *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.*
