This package provides TypeScript definitions for the 'flat' library, a utility for flattening and unflattening JavaScript objects and arrays. Using these types offers improved code editor support, static analysis, and error prevention when working with the 'flat' package in TypeScript projects. They ensure type safety when interacting with flattened data structures, defining function parameters, and managing configurations involving deeply nested objects. Enables developers to leverage the library with greater confidence and maintainability.
