   <h3>1. First-class TypeScript Support</h3>
   <p>Ember has embraced TypeScript as a first-class citizen next to JavaScript. In practice this means you can build apps using TypeScript without having to worry about incompatibility with external type definitions of Ember itself. As of version 5.1, Ember ships with built-in stable types. Read all about it and how to get started <a href="https://blog.emberjs.com/stable-typescript-types-in-ember-5-1">in the announcement post.</a> Glint, the TypeScript-powered tooling for Glimmer templates, also shipped as a stable release after two years of public preview.
