NeverThrow

Encapsulates success and failure in TypeScript types, eliminating uncaught exceptions and enabling compile-time checks, as shown in the Result<T, E> generic signatures throughout the API.

Provides combinators like map, andThen, and orElse for chainable operations, allowing complex error flows without nested conditionals, similar to promises but with error awareness.

ResultAsync wraps Promise<Result> and is thenable, enabling synchronous-style error handling for asynchronous code without manual await chaining, detailed in the asyncAndThen and asyncMap methods.

Utilities like fromThrowable and fromAsyncThrowable convert exception-throwing functions into Result-returning ones, making it safe to integrate with libraries that use throw, as demonstrated in the wrapping examples.
