How does the sync.WaitGroup type help in managing a collection of Goroutines?

  • It allows you to start and stop Goroutines explicitly.
  • It provides a way to pause and resume Goroutines.
  • It helps in creating new Goroutines.
  • It schedules Goroutines automatically.
The sync.WaitGroup type in Go is used to wait for a collection of Goroutines to finish executing. It helps in managing Goroutines by allowing you to add Goroutines to the group before they start, and then you can wait for all of them to complete using the Wait method. This is useful for scenarios where you want to ensure that all Goroutines have completed their tasks before proceeding further in your program.
