-/**
- * Page provides methods to interact with a single tab in a Browser, or an extension background page in Chromium. One Browser instance might have multiple Page instances.
- * This example creates a page, navigates it to a URL, and then saves a screenshot:
- * ```js
- * const { webkit } = require('playwright');  // Or 'chromium' or 'firefox'.
- * 
- * (async () => {
- *   const browser = await webkit.launch();
- *   const context = await browser.newContext();
- *   const page = await context.newPage();
- *   await page.goto('https://example.com');
- *   await page.screenshot({path: 'screenshot.png'});
- *   await browser.close();
- * })();
- * ```
- * The Page class emits various events (described below) which can be handled using any of Node's native `EventEmitter` methods, such as `on`, `once` or `removeListener`.
- * This example logs a message for a single page `load` event:
- * ```js
- * page.once('load', () => console.log('Page loaded!'));
- * ```
- * To unsubscribe from events use the `removeListener` method:
- * ```js
- * function logRequest(interceptedRequest) {
- *   console.log('A request was made:', interceptedRequest.url());
- * }
- * page.on('request', logRequest);
- * // Sometime later...
- * page.removeListener('request', logRequest);
- * ```
