What do you mean? Go has exceptions. Their use with errors is generally discouraged because exceptions, as the name literally implies, are technically designed for exceptional circumstances (programmer fault), not errors (environmental fault), but just like in every other language with exceptions you can do it, and even Go's own standard library uses exceptions for errors in some cases. The Go creators have even expressed openly that you should be pragmatic about it: use them for errors if it makes your code better. They are there to use.
