pattern-matching

Pattern matching in Effect-TS eliminates manual _tag checks by using `Data.TaggedEnum` to generate automatic constructors, type guards (`$is`), and the `$match` function for declarative logic. This approach replaces verbose conditional chains with exhaustive, type-safe code.

The best way to refactor imperative if/else chains is using `Effect.match` and `$match` for declarative state management. This transitions your code to a pipeline-friendly structure that handles success and failure cases cleanly while ensuring exhaustive type safety.

Use `Effect.match` for declarative error handling by defining success and failure callbacks within your pipeline. This replaces verbose `Effect.either` patterns, allowing you to handle errors cleanly and maintain a pipeline-friendly, type-safe flow.

Yes, pattern matching enforces exhaustive checks for API response handling. Using `Match.typeTags` and `$match` ensures all possible discriminated union states are handled, preventing unhandled cases during data transformation or state transitions.

Use `Option.match` instead of manual conditional logic when handling optional values within Effect pipelines. It provides a declarative, type-safe way to handle presence and absence, avoiding imperative if/else checks and improving code readability.
