Hands-on Go — Learn by Doing with Realistic Examples

👋 Hi everyone!

I'm Allison Yuri, 26 years old, currently working as a Tech Lead at Prime Secure.

I'm passionate about technology, politics, blockchain, cybersecurity, and philosophy.

🎯 Why am I here?

I started posting on DEV Community to share practical and accessible knowledge for those who want to get into programming — especially with the Go language.

🚀 Project: gostart

🔗 GitHub Repository

gostart is an open and collaborative repository aimed at teaching Go through straightforward, well-commented, and structured examples.

Each example lives in its own folder, with a main.go file and an explanatory README.md.

The goal is to learn by doing, reading, and testing.

📂 Current Structure

✅ 01_hello

Your first contact with Go — the classic Hello, World! — with explanations on package main, func main(), and fmt.Println.

✅ 02_arguments

How to capture command-line arguments using os.Args and strings.Join.

✅ 03_duplicates

Reading from the terminal using bufio.Scanner, using maps to count values, and logic to display only duplicate lines.

✅ 04_animated_gif

Generating animated images with image/gif, graphic loops, sine functions, and Lissajous curve GIFs.

📌 What's coming next?

The repository will be continuously updated with new examples such as:

• HTTP requests (net/http)
• Concurrency with goroutines and channels
• File manipulation
• Real-world API integrations

🤝 Contributions are welcome!

If you’d like to help teach Go, feel completely free to send pull requests with new examples following the current structure:

💬 Feel free to comment, suggest improvements, or ask anything.

Let’s learn together! 🚀
