About Golang
Learn Golang with practical examples covering syntax, types, functions, structs, interfaces, errors, goroutines, channels, modules, testing, and web APIs.
Prerequisites
Basic computer knowledge is enough to start. Prior programming experience is helpful but not required.
Audience
Designed for beginners, students, interview preparation, and developers who want a clear Golang path.
What You'll Learn
Core concepts, examples, common mistakes, practical patterns, FAQs, and a step-by-step learning roadmap.
Tools Needed
Use a modern browser, code editor, terminal, and the available online compiler when supported.
Golang Learning Path
Build idiomatic Go programs with explicit errors, interfaces, concurrency, cancellation, testing, and observability.
- Master packages, types, functions, and errors
- Use interfaces, goroutines, channels, context, and I/O
- Test, benchmark, profile, and ship a service
Concurrent Job Service
Build an HTTP job service with bounded workers, context cancellation, idempotent submission, graceful shutdown, and metrics.
Milestones
- Define packages, API, job state, and errors
- Add worker pool, cancellation, persistence, and shutdown
- Run race, load, timeout, and recovery tests
Completion Evidence
- Race-detector run
- Benchmark profile
- Shutdown trace
Respect Cancellation
Complete cancelled so it reports whether the supplied context has already been cancelled.
Result
Run your solution when it is ready.
Acceptance Checks
- Open context is false.
- Cancelled context is true without blocking.
Expected output
false
true
