What are data races in Go and how can I avoid them?

Data races in Go occur when two or more goroutines access the same variable concurrently, and at least one of them modifies it. To avoid them, you can use synchronization techniques like channels or the sync package.

Can you explain how to use channels to prevent data races?

Sure! Channels in Go allow goroutines to communicate safely. By sending data through channels, you can ensure that only one goroutine accesses the data at a time, thus preventing data races.

What are some common mistakes that lead to data races?

Common mistakes include sharing variables between goroutines without proper synchronization, using global variables, and not using channels effectively.

How can I detect data races in my Go code?

You can use the -race flag when running your Go program. This flag enables the race detector, which will report any data races it finds.
