   <h3>1. First-class TypeScript Support</h3>
   <p>Ember has embraced TypeScript as a first-class citizen next to JavaScript.

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.
