Functions that might fail return an error as the last return value, which must be checked by the caller. 2. How does Go handle concurrent programming? Answer: Go uses goroutines and channels for concurrent programming. Goroutines are lightweight threads, and channels are used for communication between them. 3. What are Go interfaces?

Answer: Go uses a concurrent mark-and-sweep garbage collector that runs in the background to reclaim memory allocated to objects no longer in use. 6. How do you handle dependencies in Go projects? Answer: Dependencies in Go are managed using Go modules. You can create a module with go mod init, add dependencies with go get, and tidy up the module with go mod tidy. 7. What is a pointer in Go? Answer: A pointer holds the memory address of a value. Pointers are used to share memory and data between parts of a program. 8. How do you create a new goroutine? Answer: You can create a new goroutine by prefixing a function call with the go keyword, e.g., go myFunction(). 9. What is a select statement in Go?
