> React Native doesn't provide any guarantees about the types of values in these structures. Your native module might expect array of strings, but if JavaScript calls your method with an array that contains number and string you'll get `NSArray` with `NSNumber` and `NSString`. It's the developer's responsibility to check array/map values types (see [`RCTConvert`](https://github.com/facebook/react-native/blob/master/React/Base/RCTConvert.h) for helper methods).
