Summary of my bookmarked videos from Oct 27th, 2021
- Go for JS Devs | Part 11 | Mutexes, Waitgroups, Sync Package
In this video, the presenter discusses the usage of channels as a synchronization mechanism, as well as mutexes and waitgroups in Go programming. They demonstrate how to fix issues related to concurrent map iteration and data races by coordinating access to the map using a channel and a mutex. The presenter also introduces the concept of waitgroups to ensure the completion of goroutines. They compare the use of channels and locks, emphasizing that channels are preferable when multiple processes need to communicate and share data, while locks are more suitable for scenarios where concurrent access to shared resources is required.
