Controlling new page puppeteer.js

In Puppeteer, you can control the behavior of a new page by using the page object returned by the browser.newPage() method. Here are some ways to control the behavior of a new page:

Navigation: You can navigate to a new page by calling the goto() method on the page object. For example:
```
const page = await browser.newPage();
await page.goto('https://example.com');
```
Setting the viewport: You can set the viewport size and dimensions using the setViewport() method. For example:
```
const page = await browser.newPage();
await page.setViewport({ width: 1280, height: 800 });
```

Setting the user agent: You can set the user agent string using the setUserAgent() method. For example:

const page = await browser.newPage();
await page.setUserAgent('Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3');

Disabling images: You can disable images by setting the image option to false when creating the page. For example:
```
const page = await browser.newPage({ image: false });
```
Enabling JavaScript: You can enable JavaScript by setting the javascriptEnabled option to true when creating the page. For example:
```
const page = await browser.newPage({ javascriptEnabled: true });
```
Setting the timezone: You can set the timezone using the setTimezone() method. For example:
```
const page = await browser.newPage();
await page.setTimezone('America/New_York');
```

Setting the geolocation: You can set the geolocation using the setGeolocation() method. For example:

const page = await browser.newPage();
await page.setGeolocation({ latitude: 37.7749, longitude: -122.4194 });

Waiting for a specific condition: You can use the waitFor() method to wait for a specific condition to be met. For example:
```
const page = await browser.newPage();
await page.goto('https://example.com');
await page.waitFor('h1');
```
Cancelling a navigation: You can cancel a navigation by calling the cancel() method on the page object. For example:
```
const page = await browser.newPage();
await page.goto('https://example.com');
page.cancel();
```
Closing the page: You can close the page by calling the close() method on the page object. For example:
```
const page = await browser.newPage();
await page.goto('https://example.com');
page.close();
```
These are just a few examples of how you can control the behavior of a new page in Puppeteer. You can find more information in the Puppeteer documentation.
