Go Learning Journey

This repository documents my journey learning the Go (Golang) programming language. Starting from scratch, running on Debian 13, and mentored by Gemini AI.

📌 Learning Plan (Roadmap)

Phase 1: Foundations (Syntax & Logic)

• 01. Hello Gopher: Installation, go mod, and the first program.
• 02. Variables & Data Types: Declarations (var, :=), constants, and zero values.
• 03. Control Flow: Conditionals (if, switch) and the one and only loop (for).

• 04. Basic Functions: Parameters, multiple return values, and named return values.

Phase 2: Data Structures & Memory Management

• 05. Arrays & Slices: Understanding static vs. dynamic data collections.
• 06. Maps: Storing data in key-value formats.
• 07. Pointers: Understanding memory addresses and when to use them.

• 08. Structs: Creating custom data types to represent objects.

Phase 3: Go-Style Object-Oriented Programming

• 09. Methods: Attaching functions to structs.
• 10. Interfaces: Behavioral contracts and the power of polymorphism in Go.

• 11. Error Handling: The philosophy of handling errors without try-catch.

Phase 4: Advanced Features & Concurrency

• 12. Packages & Modules: Managing dependencies and large project structures.
• 13. Goroutines: The fundamentals of concurrency (parallel processing).
• 14. Channels: The safe way for goroutines to communicate.

• 15. Select & WaitGroups: Synchronizing complex concurrency patterns.

Phase 5: Go for the Real World (Systems & Web)

• 16. Standard Library: String manipulation, time, and file I/O on Debian.
• 17. JSON & Web APIs: Building HTTP servers and processing JSON data.
• 18. Unit Testing: Writing automated tests using the testing package.

• 19. Database Connectivity: Connecting Go with SQL (PostgreSQL/MySQL).

Phase 6: Final Project

• Capstone Project: Building a functional CLI application or REST API.
