Show all headers | View raw

Hi, looking at some React Native examples and I see things like this:

const {
   FooterComponent,
   HeaderComponent,
   ItemComponent,
   ListEmptyComponent,
   ItemSeparatorComponent,
   PlainInput,
   SeparatorComponent,
   Spindicator,
   genItemData,
   getItemLayout,
   pressItem,
   renderSmallSwitchOption,
} = require('./ListExampleShared');

or this:

const {
   Animated,
   Image,
   Platform,
   TouchableHighlight,
   StyleSheet,
   Switch,
   Text,
   TextInput,
   View,
} = ReactNative;

What is this? Some kind of import? Can anyone explain the logic behind this?

Thank you
