## What it is
Ember.js is a batteries-included JavaScript framework for building ambitious web applications, featuring a best-in-class router, Ember Data, HTML-first components, and Ember CLI tooling. It emphasizes convention over configuration, developer productivity, and long-term stability with regular LTS releases.

## Use cases
- build a single-page web application with routing
- create a large-scale web app with a built-in data layer
- scaffold a full-stack-ready frontend project with generators
- build rich UIs that work on any device
- develop a long-lived web app with LTS security support
- manage complex nested URLs with async data loading

## When to choose
- you want an opinionated, batteries-included framework with routing, data, and build tooling out of the box
- you need long-term stability, LTS releases, and a mature ecosystem for a long-lived app
- your team values convention over configuration and strong documentation
- you need best-in-class URL routing with nested routes and async data loading

## When to avoid
- you prefer minimal, unopinionated libraries you assemble yourself
- you want a lightweight framework for a small static site or simple landing page
- your team is heavily invested in a different ecosystem like React or Vue
- you need fine-grained control over every architectural decision
