# Why TypeScript is a good fit for Scala developers

John and Michael argue that Scala developers can bring their experience to TypeScript without giving up typed functional effects. They discuss TypeScript's ecosystem and pragmatic type system, and Effect's typed errors, dependencies, concurrency, and telemetry.

They caution against reproducing Scala conventions instead of learning the host language. [06:50](https://youtu.be/59QbEjsaBvA?t=410) [59:41](https://youtu.be/59QbEjsaBvA?t=3581)
