Golang Learning Path for Beginners

A comprehensive tutorial series to learn Golang from basics to building a complete backend with routes.

📚 Tutorial List

1. Data Types ⭐ START HERE

Learn about Golang's basic data types: strings, integers, floats, booleans, and type conversions.

2. Arrays & Slices

Master working with collections: fixed-size arrays and flexible slices.

3. Maps

Learn key-value data structures in Golang.

4. Conditions & Loops

Control flow with if/else, switch statements, and loops.

5. Functions

Define reusable code blocks, multiple returns, and variadic functions.

6. Packages & Imports

Organize code into packages and reuse them.

7. Structs & Methods

Create custom data structures and methods.

8. Interfaces

Write flexible, polymorphic code with interfaces.

9. Error Handling

Proper error handling patterns in Golang.

10. Pointers

Understand memory, references, and pointer operations.

11. Goroutines & Channels

Master concurrent programming.

12. Backend with Routes 🎯 FINAL PROJECT

Build a REST API with GET and POST endpoints using net/http.
