 A React Native library for hashing strings using the fast and deterministic xxHash algorithm, written in C++ with JSI for high performance. This library provides support for both 64-bit and 128-bit hashing.
 
-
 ## Features
 
 - **High Performance**: xxHash is one of the fastest non-cryptographic hash functions.
 - **Deterministic Hashing**: Ensures consistent results for the same input.
 - **128-bit and 64-bit Support**: Choose between 128-bit and 64-bit hash outputs based on your use case.
 - **Cross-Platform**: Supports both iOS and Android in React Native projects.
