## What it is
Binding.scala is a reactive data-binding library for Scala that runs on both the JVM and Scala.js. It provides automatically recalculating binding expressions that serve as a foundation for building reactive UIs, including via the separate html.scala framework.

## Use cases
- build reactive user interfaces in Scala with Scala.js
- bind UI state to data that updates automatically when dependencies change
- create reactive HTML frontends without React-style virtual DOM concepts
- use data binding in ScalaFX or JavaFX applications via FXML
- share reactive data-binding logic between JVM backend and browser frontend code

## When to choose
- you are a Scala developer building reactive web or desktop UIs
- you want lightweight reactive data binding with fewer concepts than React
- you need reactive bindings on both JVM and Scala.js

## When to avoid
- you need a full batteries-included UI framework out of the box (12.x no longer bundles one; use html.scala)
- your team does not use Scala
- you prefer mainstream JavaScript ecosystem tooling

## Facets
- artifact type: library
- maturity: active
- function: state-management, frontend-framework, ui-components
- domain: web-development, frontend, cross-platform
- platform: jvm
- tags: reactive-programming, data-binding, scalajs, javafx, fxml, html-literals, functional-reactive, web-server
