## What it is
Miso is a Haskell front-end framework for building web and native user interfaces, inspired by Elm and React, using a Model-View-Update architecture with a virtual DOM. It compiles to WebAssembly or JavaScript via the GHC backends and can also target native mobile apps through the Lynx runtime.

## Use cases
- build a single-page web app in Haskell
- compile a Haskell UI to WebAssembly
- server-side render and hydrate a Haskell web app
- build a native iOS or Android app from Haskell code
- create a reactive UI with a virtual DOM diffing algorithm
- write type-safe client-side routing in Haskell
- build a component-based frontend with React-like concepts in Haskell

## When to choose
- you want to write your entire frontend in Haskell with strong static typing
- you prefer the Elm architecture / Model-View-Update pattern
- you need WebAssembly as a first-class compilation target
- you want SSR with hydration and SEO support from a Haskell server
- you want to reuse the same Haskell UI code for web and native mobile via Lynx

## When to avoid
- your team does not know Haskell or functional programming
- you need a large ecosystem of ready-made UI components and libraries
- you need fast iteration with mainstream tooling and broad community support
- your project requires tight integration with the JavaScript ecosystem rather than an FFI bridge
- bundle size and WASM startup time are critical constraints
