Does Go have callback concept?

I found many talks saying that Node.js is bad because of callback hell and Go is good because of its synchronous model.

What I feel is Go can also do callback as same as Node.js but in a synchronous way. As we can pass anonymous function and do closure things

So, why are they comparing Go and Node.js in callback perspective as if Go cannot become callback hell.

Or I misunderstand the meaning of callback and anonymous function in Go?
