Go Constants Multiple constants declaration


You can declare multiple constants within the same const block:

const (
    Alpha = "alpha"
    Beta  = "beta"
    Gamma = "gamma"

And automatically increment constants with the iota keyword:

const (
    Zero = iota // Zero == 0
    One         // One  == 1
    Two         // Two  == 2

For more examples of using iota to declare constants, see Iota.

You can also declare multiple constants using the multiple assignment. However, this syntax may be harder to read and it is generally avoided.

const Foo, Bar = "foo", "bar"
