 ## Internationalization in React (Native)

-TL;DR: There are several ways to render translations: You may use the [`Trans`](/docs/ref/react.md#trans) component or the [`useLingui`](/docs/ref/react.md#withi18n) hook together with the `t` macro. When you change the active locale or load new messages, all the components that consume the Context provided by `I18nProvider` will re-render, making sure the UI shows the correct translations.

+Until now, we have covered the [`Trans`](/docs/ref/react.md#trans) macro and the [`useLingui`](ref/react#uselingui) hook. Using them will make sure our components are always in sync with the currently active locale and message catalog.
 
 However, often you'll need to show localized strings outside of React, for example when you want to show an Alert from some business logic code.
 
 In that case you'll also need access to the `i18n` object, but you don't want to pass it around from some React component.
 Lingui uses a default i18n object instance that you can import as follows:
 
-```
+```ts
 import { i18n } from '@lingui/core';
 ```
 
-This instance is the source of truth for the active locale and the `t` macro implicitly uses this instance, unless you pass custom instance like this `` t(i18n)`some message` ``.
+This instance is the source of truth for the active locale. For string constants that will be translated at runtime, the correct approach is to use the `msg` macro as follows:
 
-What that means is that in non-react code you can just call `` t`this will be translated` `` which will render the translation for currently active locale.
+```ts
+const deleteTitle = msg`Are you sure to delete this?`
