Week 1 Step 1

Getting Started

Learning GitHub

This week, you will be going through steps to set up tools needed to be successful in this camp. If you are already familiar with some, feel free to skip to the end and complete the task to move on.

GitHub

:question: What is Github?
GitHub is a cloud-based repository hosting service that is widely used in the tech industry. It allows teams to use Git for version control, collaboration, and file management. It's a version-control system for tracking changes, managing state, and teams concurrently developing on the same files or directories. Git and Github's tools are specifically designed to make coordinating work easier, and they are one of the most popular tools among students and the industry.

Check out "The Github Flow" for more information on issues, pull requests, committing, and branches!

:exclamation: Help! I don't know how to use it and I need more information.
If you want to learn more about what it is and how to use it, try taking this GitHub Learning Lab Course. After finishing it, you will have a strong understanding of all the features GitHub has to offer.

One very important rule... Don't work on your code in the web editor. This is bad practice, and you will regret it later.

:question: What should I do instead?
Install Github Desktop and commit from your local computer. We'll go over code editors next if you don't have one to work on your code locally. You can also use git on your commandline.

:pencil: Task 1: Create a new branch, edit the README.md file with your name, and commit the change on this repository. Then, make a pull request to your main branch and merge the edits!

Key functions you should be familiar with after this task include:

:camping: To move on, make sure you commit the change and merge the branch!

Week 1 Step 2

Getting Started

Downloading an IDE

This week, you will be going through steps to set up tools needed to be successful in this camp. If you are already familiar with some, feel free to skip to the end and complete the task to move on.

Visual Studio Code

:question: What is an IDE and why do we need it?
Before we start coding, we need to install an IDE. An IDE is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of at least a source code editor, build automation tools, and a debugger. Although there are hundreds of IDEs to choose from, we are going to use Visual Studio Code due to its popularity and integration with Azure (via extensions and libraries).

:exclamation: OK, how do I install it?
To install VSC, go to: https://code.visualstudio.com/download and choose your operating system (ie. Windows, Mac, Linux, etc). Then click **Download** and run the installer (usually a `.exe` or `.zip` file). After it's installed, open it up and try it out. If you need some help navigating VSC, check out this super helpful YouTube video.

Make sure to use Dark Theme unless you want to live life on the edge...

:pencil: Task 2: Create and export a JavaScript function in a branch called week1 that returns "Hello World".

:exclamation: How do I export a function?
Let's say your function name is `hello`. To export it, add this line of code at the very bottom of your file outside of your function: `module.exports = hello`. Example: ```js function hello() { // your code } module.exports = hello ```

:question: Why do I need to export the function?
For this camp, you need to export it in order for us to test it. When you commit the file, we will try running the function by importing it like so: ```js let hello = require('../../helloworld.js') let output = hello() ``` #### How does this apply to code in the real world? Just like you can import code from modules other people have written, you can also **import functions you wrote from *other files* to reuse them.** In function oriented programming, you use functions over and over again to save code. If you want to use the function `hello()` in another file, you would need to import it.

:exclamation: Can I have more detailed steps?
1. Create a new file 2. Name the file helloworld.js 3. Write your code 4. If you have node installed on your computer, open terminal on VS Code and type 'node helloworld.js' 5. If you have not installed node on your computer, you will need to do that first: https://nodejs.org/en/download/ 6. Tip: to test your function, call it in your code. 7. Create a new branch named `week1` and commit your `helloworld.js` file in the root directory.

:camping: Make sure you export the function, and commit helloworld.js to the root directory of a new branch week1 in this repository to move on!

Note: From now on, you will never need to close an issue. The Counselor will do that for you, create new issues, and new comments for further instructions!
