#Why byethrow?

@praha/byethrow strikes a thoughtful balance in the Result type ecosystem. While there are other excellent libraries available, byethrow offers a unique combination of features that make it stand out:

#The Sweet Spot Between Simple and Powerful

• More complete than neverthrow: While neverthrow is a great library, it occasionally lacks certain features you might need in real-world applications. Byethrow fills those gaps while maintaining simplicity.
• Less complex than effect-ts/fp-ts: These libraries are incredibly powerful but can introduce unnecessary complexity and overhead for many use cases. They often require a steep learning curve and extensive knowledge of functional programming concepts.
• Better than vanilla try/catch: Traditional error handling mixes error management with business logic, making code harder to reason about and test.

#Designed for Real-World Use

Byethrow was built with practical development needs in mind:

• Team-friendly: Easy to adopt incrementally without requiring your entire team to learn advanced functional programming
• TypeScript-first: Excellent type inference and safety without sacrificing developer experience
• Performance-conscious: Lightweight runtime with excellent tree-shaking support
• Predictable: Consistent API design means less cognitive overhead when switching between projects

#Why not try/catch?

Traditional error handling in JavaScript often leads to scattered try/catch blocks and unclear control flow. Result types offer several advantages:

• Explicit Error Handling: Errors become part of your function's return type, making them impossible to ignore
• Composable Operations: Chain operations together with built-in error propagation
• Type Safety: TypeScript can track both success and error types throughout your application
• Cleaner Code: Separate your business logic from error handling concerns
