Working with Concurrency in Go (Golang)

Trevor Sawler develops concurrency through goroutines, wait groups, mutexes and channels, using classic problems before an application example. It suits learners who already understand Go and want to investigate races, coordination and early termination. Writing a program that appears to work once is insufficient evidence that its concurrent behavior is correct.

What you will learn

• Coordinate goroutines with wait groups.
• Investigate races and mutual exclusion.
• Use channels for communication.

Who this suits

A good understanding of Go is required; the course also uses Docker Desktop and a connected computer.

Before you enroll

Check the Go and dependency versions used in each example. Write and run your own tests, including invalid inputs and failure paths. Hosting, databases and cloud services may require separate accounts or fees. A working course project still needs independent security and operational review before real users depend on it.

Udemy offers paid purchase or subscription access depending on the current course and region. Paid teaching courses provide completion certificates under Udemy’s policy. Check current access terms and any separate software or material costs before enrolling.

Put it into practice

Create a deliberately unsafe shared-counter example, run the race detector and explain how your revised synchronization addresses the actual shared state.
