Elmslie is a minimalistic reactive implementation of TEA/ELM written in kotlin with java support.  

Named after [George Grant Elmslie](https://en.wikipedia.org/wiki/George_Grant_Elmslie), a Scottish-born architect.

## Why?

- **Scalable and Reusable**: Built-in support for nesting components

- **Multiplatform**: Written with pure Kotlin and Coroutines, supports KMP (Android, iOS, JS)

- **Single immutable state**: Simplify state management

- **UDF**: Say no to spaghetti code with Unidirectional Data Flow
