Go Quick Start

cd golang

# Fundamentals
go run fundamentals/01_basics/main.go

# Concurrency
go run ./concurrency/

# Interfaces deep dive
go run ./interfaces_deep/

# Testing
go test ./testing/ -v
go test ./testing/ -bench=.

# Hexagonal API (starts :8080)
go run ./web/01_hexagonal_api/

# Other topics
go run ./generics/
go run ./database/
go run ./reflection/
go run ./json_encoding/
go run ./shutdown/

Structure

• Each language folder is self-contained with its own go.mod/pyproject.toml etc
• No cross-language dependencies
• Add a language: just create a new folder at root level
