# JS Set up

It takes some work to get to the point where you can use JavaScript to manipulate the DOM. With JavaScript we can take data from a form and send it to a server, create all kinds of interesting effects and animations, and organize data in new and interesting ways.

For learning purposes, we will be working in a simple console window for these lessons, and we will not synthesize HTML, CSS, and JavaScript until Week 2 of the program. Then, we'll do more work with JavaScript in an application. Before we do that, we've got to make sure you have a solid foundation in JavaScript fundamentals.

## File Location

You should be working in the following file:

```
   javascript-library
        └── 0-PreWork
            └── 1-HTML-Basics
            └── 2-CSS-Basics
            └── 3-JavaScript-Basics
                00-setup.js       <---Work here.
```

## Node Exec

If you are jumping in here and haven't installed Node Exec yet, you'll want to grab it that package that will help us run JavaScript in a console window in Visual Studio code. Here are the instructions for doing that:

1. Click on the Extensions button.
2. Search for `Node Exec`.
3. Install the package.&#x20;
4. Inside of setup.js, on line 1, write the following statement:

   ```javascript
   console.log('Hello world!');
   ```
5. Still inside of the file, press F8 or hold the `fn` key and press F8.
6. The code should execute, and you should see the following:&#x20;

   ![Set up Test](https://930399471-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAU8Yfaa-LOM7hRx2at%2F-LBbRnL_yp_ROj7VsH7U%2F-LBbRqHFyh8NYUUxDYYN%2Fsetup-test.PNG?generation=1525375265999649\&alt=media)

## Running the Code

1. Press the debug button or `ctrl + shift + d`.
2. Press the play button in the top left.&#x20;
3. If everything goes right, you should have a console window pop up.

## Self-Assessment

In this file go ahead and write out whatever you might know about JavaScript.

* Can you write a function?&#x20;
* A for loop?&#x20;
* Can you write FizzBuzz?&#x20;
* If you can't do any of these things, leave this file blank. This is intended to be used for your personal growth.
