+## Browser context
+
+A [BrowserContext] is an isolated incognito-alike session within a browser instance. Browser contexts are fast and
+cheap to create. We recommend running each test scenario in its own new Browser context, so that
+the browser state is isolated between the tests. If you are using [Playwright Test](./intro.md), this happens out of the
+box for each test. Otherwise, you can create browser contexts manually:
+
+```js
+const browser = await chromium.launch();
+const context = await browser.newContext();
+const page = await context.newPage();
+```
+
+```java
+Browser browser = chromium.launch();
+BrowserContext context = browser.newContext();
+Page page = context.newPage();
+```
+
+```python async
+browser = await playwright.chromium.launch()
+context = await browser.new_context()
+page = await context.new_page()
+```
+
+```python sync
+browser = playwright.chromium.launch()
+context = browser.new_context()
+page = context.new_page()
+```
+
+```csharp
+await using var browser = playwright.Chromium.LaunchAsync();
+var context = await browser.NewContextAsync();
+var page = await context.NewPageAsync();
+```
+
+Browser contexts can also be used to emulate multi-page scenarios involving
+mobile devices, permissions, locale and color scheme.
+
+```js
+const { devices } = require('playwright');
+const iPhone = devices['iPhone 11 Pro'];
+
+const context = await browser.newContext({
+  ...iPhone,
+  permissions: ['geolocation'],
+  geolocation: { latitude: 52.52, longitude: 13.39},
+  colorScheme: 'dark',
+  locale: 'de-DE'
+});
+const page = await context.newPage();
+```
+
+```java

+

+// Create a Chromium browser instance
+const browser = await chromium.launch();

+id: evaluating
+title: "Evaluating JavaScript"
+---
+
+Playwright scripts run in your Playwright environment. Your page scripts run in the browser page environment. Those environments don't intersect, they are running in different virtual machines in different processes and even potentially on different computers.
+
+The [`method: Page.evaluate`] API can run a JavaScript function in the context
+of the web page and bring results back to the Playwright environment. Browser globals like
+`window` and `document` can be used in `evaluate`.
+
+```js
+const href = await page.evaluate(() => document.location.href);
+```
+
+```java
+String href = (String) page.evaluate("document.location.href");
+```
+
+```python async
+href = await page.evaluate('() => document.location.href')
+```
+
+```python sync
+href = page.evaluate('() => document.location.href')
+```
+
+```csharp
+var href = await page.EvaluateAsync<string>("document.location.href");
+```
+
+If the result is a Promise or if the function is asynchronous evaluate will automatically wait until it's resolved:
+
+```js
+const status = await page.evaluate(async () => {
+  const response = await fetch(location.href);
+  return response.status;
+});
+```
+
+```java
+int status = (int) page.evaluate("async () => {\n" +
+  "  const response = await fetch(location.href);\n" +
+  "  return response.status;\n" +
+  "}");
+```
+
+```python async
+status = await page.evaluate("""async () => {
+  response = await fetch(location.href)
+  return response.status
+}""")
+```
+
+```python sync
+status = page.evaluate("""async () => {
+  response = fetch(location.href)
+  return response.status
+}""")
+```
+
+```csharp
+int status = await page.EvaluateAsync<int>(@"async () => {
+  const response = await fetch(location.href);
+  return response.status;
+}");
+```
+
+## Evaluation Argument
+
+Playwright evaluation methods like [`method: Page.evaluate`] take a single optional argument. This argument can be a mix of [Serializable] values and [JSHandle] or [ElementHandle] instances. Handles are automatically converted to the value they represent.
+
+```js
+// A primitive value.
+await page.evaluate(num => num, 42);
+
+// An array.
+await page.evaluate(array => array.length, [1, 2, 3]);
+
+// An object.
+await page.evaluate(object => object.foo, { foo: 'bar' });
+
+// A single handle.
+const button = await page.$('button');
+await page.evaluate(button => button.textContent, button);
+
+// Alternative notation using elementHandle.evaluate.
+await button.evaluate((button, from) => button.textContent.substring(from), 5);
+
+// Object with multiple handles.
+const button1 = await page.$('.button1');
+const button2 = await page.$('.button2');
+await page.evaluate(
+    o => o.button1.textContent + o.button2.textContent,
+    { button1, button2 });
+
+// Object destructuring works. Note that property names must match
+// between the destructured object and the argument.
+// Also note the required parenthesis.
+await page.evaluate(
+    ({ button1, button2 }) => button1.textContent + button2.textContent,
+    { button1, button2 });
+
+// Array works as well. Arbitrary names can be used for destructuring.
+// Note the required parenthesis.
+await page.evaluate(
+    ([b1, b2]) => b1.textContent + b2.textContent,
+    [button1, button2]);
+
+// Any non-cyclic mix of serializables and handles works.

+## Frames
+
+A [Page] can have one or more [Frame] objects attached to it. Each page has a main frame and page-level interactions
+(like `click`) are assumed to operate in the main frame.
+
+A page can have additional frames attached with the `iframe` HTML tag. These frames can be accessed for interactions
+inside the frame.
+
+```js
+// Locate element inside frame
+const username = await page.frameLocator('.frame-class').locator('#username-input');
+await username.fill('John');
+```
+
+```java
+// Locate element inside frame
+Locator username = page.frameLocator(".frame-class").locator("#username-input");
+username.fill("John");
+```
+
+```python async
+# Locate element inside frame
+username = await page.frame_locator('.frame-class').locator('#username-input')
+await username.fill('John')
+```
+
+```python sync
+# Locate element inside frame
+# Get frame using any other selector
+username = page.frame_locator('.frame-class').locator('#username-input')
+username.fill('John')

+var username = await page.FrameLocator(".frame-class").Locator("#username-input");
+await username.FillAsync("John");

+// Get frame using the frame's name attribute
+const frame = page.frame('frame-login');
+
+// Get frame using frame's URL
+const frame = page.frame({ url: /.*domain.*/ });
+
+// Get frame using any other selector
+const frameElementHandle = await page.$('.frame-class');
+const frame = await frameElementHandle.contentFrame();
+

+
+// Get frame using frame"s URL
+Frame frame = page.frameByUrl(Pattern.compile(".*domain.*"));
+
+// Get frame using any other selector
+ElementHandle frameElementHandle = page.querySelector(".frame-class");
+Frame frame = frameElementHandle.contentFrame();
+
+// Interact with the frame
+frame.fill("#username-input", "John");
+```

-## Multiple contexts
+## Pages
 
-[Browser contexts](./core-concepts.md#browser-contexts) are isolated environments on a single browser instance.
+Each [BrowserContext] can have multiple pages. A [Page] refers to a single tab or a popup window within a browser
-Playwright can create multiple browser contexts within a single scenario. This is useful when you want to test for
+context. It should be used to navigate to URLs and interact with the page content.
