Go Switch

This lesson is part of Go · All levels

Summary

This lesson discusses switching as a neat way to handle many conditions in Go. Every case doesn't need a break because Go doesn't do an automatic fallthrough, and you can write multiple values into one case. Go also supports unconditional switches that work like if-else chains, as well as fallthrough keywords when trying to force the next execution case.

Key points

Switch case in Go does not automatically fall to the next case (without automatic break)
One case can contain several values separated by a comma
The switch without the expression functions as an if-else if sequence.
Fallthrough forced the next execution of the contents of the case
