## Resource

Explore the design philosophy of ReScript, a strongly typed language that compiles to JavaScript with a focus on simplicity and fast feedback loops. Learn how its sound type system and native error handling provide a more maintainable alternative to TypeScript.

## Highlights
- Main idea: ReScript prioritizes a small, simple language surface area to ensure high maintainability and fast compilation
- Practical takeaway: Use ReScript's native Result and Option types to enforce exhaustive error handling across your entire call stack
- Failure mode: Avoid treating JavaScript interop as a 1:1 mapping; writing effective bindings is an art that requires tailoring APIs to ReScript's strengths
- Main idea: The language leverages polymorphic variants and structural typing to track possible error states automatically through inference
- Practical takeaway: ReScript version 12 is moving toward a more JavaScript-centric identity by cleaning up legacy build systems and optimizing for the modern web
