If the name is empty, it will return true otherwise it will return false. The IsEmpty() method will have the receiver type as Asset. This means that we can call this method by using the Asset type. This method will return a boolean value. This method will have the following signature:7func (a Asset) IsEmpty() bool8The IsEmpty() method will check if the name of the asset is empty or not. If the name is empty, it will return true otherwise it will return false. The IsEmpty() method will have the receiver type as Asset. This means that we can call this method by using the Asset type. This method will return a boolean value. This method will have the following signature:9func (a Asset) IsEmpty() bool {10    if a.Name == "" {11    }12}13In this tutorial, we have learned how to create a method in Go. We have created a method called IsEmpty() in the Asset class. This method will return true if the name of the asset is empty otherwise it will return false. We have called this
