This JSON object contains two keys, `language` and `mascot`. Following these keys are the associated values. Here the `language` key has a value of `Go` and `mascot` is assigned the value `Gopher`.
The JSON encoder in the standard library makes use of struct tags as annotations indicating to the encoder how you would like to name your fields in the JSON output. These JSON encoding and decoding mechanisms can be found in the `encoding/json` [package](https://godoc.org/encoding/json).

The only thing we've changed in this example from previous ones is that the password field now uses the special `"-"` value for its `json:` struct tag. In the output from this example that the `password` field is no longer present.
These features of the `encoding/json` package, `,omitempty` and `"-"`, are not standards. What a package decides to do with values of a struct tag depends on its implementation. Because the `encoding/json` package is part of the standard library, other packages have also implemented these features in the same way as a matter of convention. However, it's important to read the documentation for any third-party package that uses struct tags to learn what is supported and what is not.
