## What it is
WinJS (Windows Library for JavaScript) is a UI toolkit of polished JavaScript controls and utilities for building HTML/CSS/JS applications in modern browsers, originally from Microsoft. It emphasizes touch, mouse, keyboard, and accessibility support, but is now in maintenance mode with no new feature investment.

## Use cases
- build web apps with polished Windows-style UI controls
- add touch-friendly accessible UI components to a web app
- maintain an existing WinJS-based application
- build HTML/JS/CSS apps with a cohesive component set
- get high-performance list, grid, and navigation controls for the browser

## When to choose
- you are maintaining or extending an existing WinJS-based app
- you want Windows-flavored, accessibility-ready UI controls in plain HTML/JS/CSS
- you need a stable, no-longer-changing toolkit for legacy browser apps

## When to avoid
- you need a library with active development and new features
- you are starting a new modern web project (prefer React, Vue, or similar)
- you need framework integrations or a modern build ecosystem

## Facets
- artifact type: library

- domain: web-development, frontend, cross-platform
