Let's walk through the process of downloading p5.js and take a peek at the goodies inside the package.

Downloading p5.js

Getting p5.js is like grabbing a slice of digital pizza; it's easy, and there are a few toppings (options) to choose from.

1. Visit the p5.js Website: Head over to the official p5.js website. You'll be greeted with a friendly download button.

2. Choose Your Flavor: You'll see a few options:

   • Complete: Includes everything you need (the library, examples, and the p5.js Editor).
   • p5.js: Just the core library.
   • p5.dom and p5.sound: Additional libraries for DOM manipulation and sound.

3. Download the Complete Package: For this guide, we'll go with the "Complete" option. Click the download button and save the ZIP file to your computer.

4. Unzip the File: Once the download is complete, unzip the file. You'll see a folder named something like p5.zip (or whatever creative name you've given it). Extract it to a location where you can easily find it.

Voilà! You've got p5.js on your machine. Time to explore the treasure chest!

What's Inside the Download?

Opening the unzipped folder is like opening a box of assorted chocolates—there's a bit of everything, and each piece has its own unique flavor.

The Core Library

The heart of p5.js is in the lib folder. Inside, you'll find:

• p5.js: The main library file. This is your go-to for all the creative coding magic.
• p5.min.js: The minified version of the library. It's smaller in size and faster to load, perfect for production environments.

Additional Libraries

In the addons folder, you'll find extra tools to enhance your projects:

• p5.dom.js: This library helps you interact with HTML elements.
• p5.sound.js: Unleash the power of audio, making your projects not just visual but also auditory experiences.

Examples

The examples folder is like a cookbook filled with recipes. It contains numerous example sketches that demonstrate what p5.js can do. Each folder inside examples is a sketch that you can run and tinker with.

The p5.js Editor

The complete package also includes the p5.js Editor, a simple coding environment designed specifically for p5.js. It's a great place to start if you're new to coding or want a hassle-free setup.

Reference Materials

Finally, you'll find documentation and reference materials in the docs folder. This is your encyclopedia of p5.js, filled with descriptions, examples, and explanations of every function and feature.

Setting Up Your First Sketch

Let's get our hands dirty with a simple sketch. We'll create a basic drawing to ensure everything is working smoothly.

1. Open the p5.js Editor: Navigate to the editor folder and launch the p5.js Editor.

2. Create a New Sketch: Click on "File" and then "New." A blank sketch will open up.

3. Write Some Code: Enter the following code into the editor:

   function setup() {
       createCanvas(400, 400);
   }
   
   function draw() {
       background(220);
       ellipse(200, 200, 50, 50);
   }
   

   This code creates a canvas and draws a circle in the center. It's simple but powerful—a great starting point for your creative journey.

4. Run the Sketch: Click the play button (triangle icon) at the top of the editor. You should see a canvas with a circle in the middle.

Congratulations! You've just created your first p5.js sketch. From here, the only limit is your imagination.

Conclusion

Downloading p5.js is the first step on a journey filled with endless creative possibilities. Whether you're making interactive art, animations, or visualizations, p5.js provides the tools you need. Now that you know how to download and set up the library, it's time to start experimenting and creating.

Happy coding!
