FBT Internationalization Framework Runtime

FBT (Facebook's Internationalization Framework) provides a JavaScript runtime for building grammatically correct, translatable user interfaces. Currently at version 1.0.2, this package handles the client-side execution of FBT-transformed strings. It doesn't provide translations itself but offers the APIs to manage them. FBT differentiates itself by enabling translatable text to reside directly within JSX, enhancing searchability and developer experience. It robustly supports complex localization features like plural variations, gender-based pronouns, and enumerations natively. The framework leverages Babel plugins during the build process to extract strings and generate optimized translation payloads, which are then utilized by this runtime package.
