 ### Expandable Hovers for JavaScript and TypeScript (preview)
 
-<!-- TODO: mjbvz -->
+We've continued to iterate on the expandable hover feature for JavaScript and TypeScript. This feature lets you use a `+` and `-` in the hover widget to show more or less type information information.
+
+<video src="images/1_100/expandable-hover.mp4" title="TypeScript Expandable Hover" autoplay loop controls muted></video>
+
+This feature is still experimental but you can try it today by enabling `setting(typescript.experimental.expandableHover)`. You must be using TypeScript version 5.9 or above, for example by installing the [TypeScript nightly extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode.vscode-typescript-next).
