What is the impact of mutability on concurrency in programming?

Mutability can lead to issues like race conditions and data inconsistency in concurrent programming. When multiple threads modify shared mutable data, it can result in unpredictable behavior.

Can you explain what race conditions are?

A race condition occurs when two or more threads access shared data and try to change it at the same time. The final outcome depends on the timing of their execution, which can lead to unexpected results.

How can I avoid race conditions in my code?

You can avoid race conditions by using synchronization mechanisms like locks, semaphores, or by using immutable data structures that prevent changes once created.

Are there any programming languages that handle mutability and concurrency better than others?

Yes, languages like Rust and Erlang are designed with concurrency in mind and provide features that help manage mutability safely, reducing the risk of race conditions.
