Struct tags are small pieces of metadata attached to fields of a struct that provide instructions to other Go code that works with the struct. When you read information from systems such as databases, or APIs, you can use struct tags to control how this information is assigned to the fields of a struct.

Panics are unforeseeable errors that will spontaneously terminate and exit a running Go program. Common mistakes are often responsible for creating panics.

We’ll also use defer statements along with the recover function to capture panics before they have a chance to unexpectedly terminate our running Go programs.
