Learn Go (Golang) Go 🚀

Welcome to the learn-go repository! This project was originally created as course material to teach the Go programming language. I've decided to leave it public as a resource for anyone interested in learning Go.

The repository is structured into sequential folders, each covering a specific topic, from the very basics to more advanced concepts like building a RESTful API.

How to Use This Repository

This repository is structured for simplicity. Almost every .go file inside the topic folders (00 to 14) is a self-contained example with its own main function.

To avoid the complexity of creating separate modules for each example, please follow these steps to run any file:

1. Choose an example you'd like to run from one of the folders (e.g., 01-variaveis/01-declaracao-de-variaveis.go).

2. Copy the entire content of that file.

3. Paste the content into the main.go file located in the root of this repository, completely replacing what's there.

4. Open your terminal in the repository's root directory and execute the following command:

   go run main.go

Important Note on Language

Please be aware that the code comments are written in a mix of Portuguese (pt-br) and English.
