Using mutexes to guard Go channels is unnecessary and can be counterproductive. Channels have built-in synchronization and handling for concurrent access. Manually guarding them with mutexes can lead to duplicate synchronization logic and make the code more complex and error-prone. For cleaner and more efficient concurrent code, avoid using mutexes to lock and unlock channels. Instead, rely on the channel's inherent synchronization mechanisms. This eliminates redundant locking operations.
