 * Returns the set of [dependency-injection providers](guide/glossary#provider)

 *
 * @usageNotes
 *
 * The function is useful when you want to bootstrap an application using
 * the `bootstrapApplication` function, but you need to disable animations
 * (for example, when running tests).
 *
 * ```typescript
 * bootstrapApplication(RootComponent, {
 *   providers: [
 *     provideNoopAnimations()
 *   ]
 * });
 * ```
 *
 * @publicApi
