What is a race condition and how does Go help to detect it?

A race condition occurs when multiple threads or goroutines access and modify shared data simultaneously without proper synchronization, leading to unpredictable program behavior.

In Go, there is a built-in tool for detecting such issues — the race detector. It can be enabled during compilation or test runs with the -race flag:

go run -race main.go

The race detector monitors memory accesses and signals potential race conditions, helping developers identify and fix synchronization errors.

This is especially important in concurrent Go programs that use goroutines and channels to avoid subtle bugs and ensure correct operation.
