Cats Effect Insights

What is Cats Effect?

Cats Effect is a purely functional runtime system for building concurrent and resilient applications in Scala. It provides abstractions like `IO` for managing side effects, concurrency primitives (e.g., `Ref`, `Deferred`), and resource management capabilities. It is commonly used for building high-performance, asynchronous systems where predictability and control over side effects are crucial.
