# Effect Meetup SF 2023: Why Effect?

Michael presents Effect as a missing standard library for TypeScript, bringing typed errors and requirements, structured concurrency, observability, resource safety, and composition into one runtime. [01:44](https://youtu.be/BqUnsDnMnMo?t=104) [02:31](https://youtu.be/BqUnsDnMnMo?t=151)

A Remix demo contrasts manual telemetry and nested error handling with Effect context, Schema, spans, metrics, and retry policies. [22:37](https://youtu.be/BqUnsDnMnMo?t=1357) [30:34](https://youtu.be/BqUnsDnMnMo?t=1834)
