Thread Synchronization

Imagine you're building a web server that processes incoming requests. Each request is handled by a different thread, but they all need to access shared resources, like a database connection or an in-memory cache.
If two threads try to modify a shared resource simultaneously, you could end up with corrupted data or unexpected behavior. This is where thread synchronization comes into play.
It helps ensure that when one thread is working with a shared resource, others are either blocked or safely accessing their own separate instances.
