Using these type definitions enables type-safe usage of stream-meter in TypeScript projects, providing autocompletion and compile-time error checking for its API, improving code quality and preventing runtime errors related to incorrect usage of the library. It defines the correct interfaces and types for creating and interacting with stream-meter instances.
