The for statements

As a language related to the C-family, Go also supports for loop style control structures. However, as you may have come to expect by now, Go's for statements work interestingly differently and simply. The for statement in Go supports four distinct idioms, as summarized in the following table:

For Statement	Usage
For condition	Used to semantically replace while and do...while loops: for x < 10 { ... }
