Discussion on: Language Features: Best and Worst

The property tags in Go:

type Invitation struct {
    InvitationToken string `json:"invitationToken" db:"invitation_token"`
}

The fact that I can have a variable called InvitationToken in Go, that is called invitationToken in JSON and invitation_token in my database is just absolutely amazing. It resolves one of my biggest pet peeves in programming, which is mixing naming cases.

This is basically just metadata that you can attach to a variable, right?

That's the gist of it yes. I think you could implement the same thing with tagged template literals in JS, but Go just offers it natively. 🤓

In js you would use decorators, which are native langage features:

class Invitation {
  @Serialize({ json: 'invitationToken', db: 'invitation_token' })
  token
}
