Enable the Go Race Detector by running tests or builds with the -race flag to identify and fix concurrent memory access issues.
Run your tests or build with the -race flag to enable the Go Race Detector, which will identify concurrent access to the same memory location without proper synchronization.
go test -race ./...
The output will show the file, line number, and goroutine IDs involved in the race, allowing you to add mutexes or channels to protect the shared data.
A race condition happens when two parts of your program try to read or write the same piece of data at the exact same time, causing unpredictable results. The race detector acts like a safety inspector that watches your code while it runs and stops it the moment it sees this dangerous overlap. You use it during development to find and fix these hidden bugs before they cause crashes in production.
