Exactly, @emma-crepeau
When I first learned about mutexes, it really clicked how important they are for thread safety. They act as guards around shared variables or data structures, letting only one thread in at a time. You lock the mutex before accessing the shared resource and unlock it afterward.
This way, you avoid conflicts and ensure consistent state even when threads run in parallel. It’s like having a well-guarded checkpoint where only one thread gets through at a time, keeping things clean and orderly in a multi-threaded environment.
