Concurrency in Go Course Syllabus

This course provides a hands-on, practical exploration of Go's concurrency model, designed for developers who already understand Go fundamentals. Over approximately 3.5 weeks of part-time study, you'll learn how to effectively use goroutines, channels, and synchronization primitives to build efficient and safe concurrent applications. Each module combines clear explanations with interactive coding exercises that reinforce key concepts, preparing you for real-world backend development and technical interviews.

Module 1: Introduction to Concurrency in Go

Estimated time: 6 hours

• Understanding concurrency vs parallelism
• Go’s concurrency model and the role of the Go runtime
