Mutex

Explore how mutexes provide exclusive locking to protect critical sections in Go concurrent programming. Understand why and how to use mutexes to guard shared data, avoid race conditions, and maintain thread safety, while balancing performance by limiting critical section scope.

What is mutex?

Let’s assume that we want a piece of code to be accessible by only one goroutine at a time. We’ll need to have a locking and unlocking mechanism that can be enabled and implemented using a mutex.

We can lock and unlock a block of code with a mutex. The section locked inside a mutex is a critical section. Mutexes can also be used to protect caches, states, and registers from concurrent access.
