React-Native apps may/often will bundle huge minified javascript file that contain application source code (thus hard to compare it), on tested app it exists in `index.android.bundle` file on android app (APK) and `main.jsbundle` file on ios app (IPA). both files return for file: `ASCII text, with very long lines` both files content start with: `var __BUNDLE_START_TIME__=` as the file-extension can be changed during compiliation (may be set to not default values) it will be better to have mechanism that detect minified javascript files and apply the js comparator for them, the test `source-contains-prebuilt-javascript-object` from lintian tool probably can be used for this. otherwise/meanwhile a solution just for react-native apps compiled with default settings will be: for `.jsbundle` extension or filename `index.android.bundle` use js comparator as done for .js files.
