It enables animation capabilities in Angular applications by providing support for Angular's animation system in the browser environment.

How do you import <code>BrowserAnimationsModule</code> in an Angular app?

You import it from <code>@angular/platform-browser/animations</code> and add it to the <code>imports</code> array of your root module or any feature module where animations are needed.

Why should you import <code>BrowserAnimationsModule</code> only once in your Angular app?

Because importing it multiple times can cause unexpected behavior or performance issues. It is designed to be a singleton module for the whole app.

What happens if you use Angular animations without importing BrowserAnimationsModule?

Animations will not run, and Angular may throw errors or warnings because the animation engine is not enabled in the browser environment.
