 * The Sentry Browser SDK Client.
 *
 * To use this SDK, call the {@link init} function as early as possible when
 * loading the web page. To set context information or send manual events, use
 * the provided methods.
 *
 * @example
 *
 * ```
 *
 * import { init } from '@sentry/browser';
 *
 * init({
 *   dsn: '__DSN__',
 *   // ...
 * });
 * ```
 *
 * @example
 * ```
 *
 * import { configureScope } from '@sentry/browser';
 * configureScope((scope: Scope) => {
 *   scope.setExtra({ battery: 0.7 });
 *   scope.setTag({ user_mode: 'admin' });
 *   scope.setUser({ id: '4711' });
 * });
 * ```
 *
 * @example
 * ```
 *
 * import { addBreadcrumb } from '@sentry/browser';
 * addBreadcrumb({
 *   message: 'My Breadcrumb',
 *   // ...
 * });
 * ```
 *
 * @example
 *
 * ```
 *
 * import * as Sentry from '@sentry/browser';
 * Sentry.captureMessage('Hello, world!');
 * Sentry.captureException(new Error('Good bye'));
 * Sentry.captureEvent({
 *   message: 'Manual',
 *   stacktrace: [
 *     // ...
