What tools are available in Go for detecting data races?

In Go, the built-in tool called the race detector is used to detect data races. It can be enabled during compilation and testing or running programs using the -race flag.

Example of running tests with the race detector:

go test -race ./...

Or running a program:

go run -race main.go

The race detector analyzes the program execution and reports cases of concurrent access to the same variables from different goroutines without synchronization.

Additionally, to localize and eliminate races, you can use:

• Profilers and tracers (pprof, trace).
• Static code analysis tools.

But the main and simplest way is to run with the -race flag, which is built into the standard Go tool and requires no additional setup.
