in the source file / Libraries/react-native/react-native-implementation.js of react-native, all modules are exported as follows:

const ReactNative = {
    // Components
    get AccessibilityInfo() { return require("AccessibilityInfo"); },
    get ActivityIndicator() { return require("ActivityIndicator"); },
    ...
}

here we use getter to export, and perform require operation inside the method. Does anyone know the difference between the above export method and the following export method?

const AccessibilityInfo = require("AccessibilityInfo");
const ActivityIndicator = require("ActivityIndicator");

const ReactNative = {
    // Components
    AccessibilityInfo,
    ActivityIndicator
    ...
}

Thank you!
