I would like some guidance on the correct way to add concurrency to my project
Hello! I am learning Go and one project I have been working on is making a network scanner utility like nmap just to learn the language. I have a working-ish version but there is currently no concurrency. I'm struggling with how to approach it, even given great examples like https://github.com/jboursiquot/portscan
- Great talk on concurrency patterns (for everyone)
