@sentry/utils provides a collection of utility functions used across Sentry's JavaScript SDKs. These tools handle common tasks like data processing, environment detection, error handling, and string manipulation, ensuring consistency and efficiency in Sentry's various integrations (Browser, Node, React Native). They offer standardized ways to perform platform-specific logic and data sanitization. @sentry/utils reduces code duplication and helps maintain a robust and reliable foundation for Sentry's error monitoring capabilities.
