Result Type — Safe Error-Returning APIs
`Result<T>` wraps "success or thrown exception" without forcing the caller into try/catch. `runCatching { ... }` is the standard producer.

Rust
Result Combinators + the ? Operator
`Result<T, E>` chains like `Option`. The `?` operator unwraps `Ok` or early-returns the `Err`, converting via `From` so callers can use one error type for many sources.
TypeScript
safeJsonParse — Result-Typed
Parse JSON without ever throwing. Returns a Result-like discriminated union so callers must handle both success and failure paths at compile time.
Go
Generic Result / Option Type
Go doesn't have built-in Result types, but generics make them ergonomic. Combine with `errors.Is` and you have type-safe railroaded error handling.
TypeScript
Result / Either Type
Encode "this might fail" in the type signature instead of throwing. Force the caller to handle both branches at compile time. Better than try/catch for foreseeable failures.
