/**
 * Interface used by Angular to control the change detection strategy for an application.
 *
 * Angular implements the following change detection strategies by default:
 *
 * - {@link DynamicChangeDetection}: slower, but does not require `eval()`.
 * - {@link JitChangeDetection}: faster, but requires `eval()`.
 *
 * In JavaScript, you should always use `JitChangeDetection`, unless you are in an environment that
 *has
 * [CSP](https://developer.mozilla.org/en-US/docs/Web/Security/CSP), such as a Chrome Extension.
 *
 * In Dart, use `DynamicChangeDetection` during development. The Angular transformer generates an
 *analog to the
 * `JitChangeDetection` strategy at compile time.
 *
 *
 * See: {@link DynamicChangeDetection}, {@link JitChangeDetection},
 * {@link PreGeneratedChangeDetection}
 *
 * # Example
 * ```javascript
 * bootstrap(MyApp, [bind(ChangeDetection).toClass(DynamicChangeDetection)]);
 * ```
