Practical uses
- Develop high-performance web server.
- Write performant and portable CLI tool.
- Build cloud-native infrastructure and orchestration.
- Implement concurrent workers.
Pros and cons
What Go does especially well — and the limits to anticipate.
Pros
- Fast compilation and single static binary production.
- Ultra-performant goroutines for concurrency.
- Simple language with minimal boilerplate.
- Complete standard library and robust cross-platform.
- Widely used in Kubernetes, Docker, Terraform.
Cons
- No native elegant GUI (possible but complex).
- Less expressive than Python or Ruby.
- Fragmented package ecosystem vs Rust or C++.
- Learning curve for advanced concurrency.
Go: when it makes sense.
Go excels for cloud infrastructure and scalable backend; for web frontend or desktop, a more specialized language is better suited.
Keep if
You build cloud-native services or microservices.. You appreciate simple syntax and fast learning curve.
Challenge if
You build primarily desktop GUI applications.. You prefer more expressive languages (Ruby, Python).
