How can data races be identified in program code?

In Go, the built-in tool for detecting race conditions is the race detector. It can be enabled during compilation and program execution using the -race flag.

Example of running:

go run -race main.go

Or during testing:

go test -race ./...

This tool monitors concurrent access to shared variables without synchronization and outputs warnings about races.

Additionally, static code analysis can be used, and critical sections can be carefully designed using mutexes (sync.Mutex), channels, and other synchronization tools to minimize the likelihood of races.
