# String Week Challenge - Day 3

Hey, hey, here we are again! Today continues week 1 of my daily challenges in October. Welcome back!

### ⏰ Need to do some catching up?

If this is the first challenge you're seeing, welcome! My challenges build on each other throughout the week, starting on Saturday and building towards a final solution on Friday. Check out the challenges for [Day 1](https://blog.barbaralaw.me/huntober-2022-day-1) and [Day 2](https://blog.barbaralaw.me/huntober-2022-day-1) then come on back.

## ⭐ 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 3

**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.**

Yesterday you should have come up with a few specific characters that we'll need today. Let's refer to those as our key characters.

We need to create a function that will **replace any instances of any of the key characters in a given string with an empty space (' ')**. See below for an example with an example set of key characters. 

**Remember to keep your code somewhere safe, as you'll need it to decrypt this week's message!**

```
example key characters -> 'A','_','K','E','Y','!'

'AyouEcould!thinkKthisAisYhard_toYreadKbeforeYreplacingEthe_keyYcharacters'
// implement key replacement function
' you could think this is hard to read before replacing the key characters'
```

*You didn't think I'd just give you the key for the week and let you skip [Day 2](https://blog.barbaralaw.me/huntober-2022-day-1), did you?*

## 🕵️ Thank You for playing along!

Before you head off to play with some string, I want to take a moment to thank those who have commented on the blog posts, shared likes, or tweeted about the daily challenges. It's been a huge joy for my deeply weird self to just create these ridiculous tasks, but knowing that even a few others are enjoying them means so much!

#### *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.*
