  Dynamic argument values are expected to be strings but it allows `null` as a special value that explicitly indicates that the binding should be removed. Other types will be treated as mistakes and will trigger a warning. So null value can be applied for v-bind and v-on.
 205. ### Can I use dynamic directive null value for slots?
  No. It can be applied only for v-bind and v-on but not v-slot. This is because v-slot is not a binding and cannot be removed.

+
+ <div id="app">
+ <p>{{ $t("user.message") }}</p>
+ </div>
+ ```

+ ```javascript
+ // Ready translated locale messages
+ const messages = {
+ en: {
+ user: {
+ message: 'Good morning'
+ }
+ },
+ de: {
+ user: {
+ message: 'Guten Morgen'
+ }
+ }
+ }
+
+ // Create VueI18n instance with options
+ const i18n = new VueI18n({
+ locale: 'de', // set locale
+ messages, // set locale messages
+ })
+
+
+ // Create a Vue instance with `i18n` option
+ new Vue({ i18n }).$mount('#app')
+
+ ```
