In Go, the main goroutine often needs to wait for other goroutines to finish their tasks before continuing execution or exiting the program.sync.WaitGroup is commonly used for waiting for a group of goroutines to finish tasks.Example code demonstrates using sync.WaitGroup to synchronize multiple goroutines.Channels can be used for passing signals between goroutines to coordinate their execution.Context allows graceful control of goroutine exits and is useful for scenarios requiring cancellation or timeouts.errgroup is recommended as it combines WaitGroup functionality with error handling for waiting for tasks and handling errors.Using sync.WaitGroup is simple and efficient, but errgroup is more elegant and supports error propagation.time.Sleep is not recommended for waiting on tasks to finish as it lacks accurate synchronization compared to sync tools.Choose the synchronization method based on specific requirements such as error handling, cancellation, or number of tasks.Leapcell offers a serverless hosting platform for Go projects with multi-language support, cost efficiency, and scalability.
