## Version 1.14

#### ⚡️ New "strict" mode

Selector ambiguity is a common problem in automation testing. **"strict" mode**
ensures that your selector points to a single element and throws otherwise.

Set `setStrict(true)` in your action calls to opt in.

```csharp
// This will throw if you have more than one button!
await page.ClickAsync("button", new Page.ClickOptions().setStrict(true));
```

#### 📍 New [**Locators API**](./api/class-locator)

Locator represents a view to the element(s) on the page. It captures the logic sufficient to retrieve the element at any given moment.

The difference between the [Locator](./api/class-locator) and [ElementHandle](./api/class-elementhandle) is that the latter points to a particular element, while [Locator](./api/class-locator) captures the logic of how to retrieve that element.

Also, locators are **"strict" by default**!

```csharp
var locator = page.Locator("button");
await locator.ClickAsync();
```

Learn more in the [documentation](./api/class-locator).

#### 🧩 Experimental [**React**](./selectors#react-selectors) and [**Vue**](./selectors#vue-selectors) selector engines

React and Vue selectors allow selecting elements by its component name and/or property values. The syntax is very similar to [attribute selectors](https://developer.mozilla.org/en-US/docs/Web/CSS/Attribute_selectors) and supports all attribute selector operators.

```csharp
await page.ClickAsync("_react=SubmitButton[enabled=true]");
await page.ClickAsync("_vue=submit-button[enabled=true]");
```

Learn more in the [react selectors documentation](./selectors#react-selectors) and the [vue selectors documentation](./selectors#vue-selectors).

#### ✨ New [**`nth`**](./selectors#n-th-element-selector) and [**`visible`**](./selectors#selecting-visible-elements) selector engines

- [`nth`](./selectors#n-th-element-selector) selector engine is equivalent to the `:nth-match` pseudo class, but could be combined with other selector engines.
- [`visible`](./selectors#selecting-visible-elements) selector engine is equivalent to the `:visible` pseudo class, but could be combined with other selector engines.

```csharp
// select the first button among all buttons
await button.ClickAsync("button >> nth=0");
// or if you are using locators, you can use First, Nth() and Last
await page.Locator("button").First.ClickAsync();

// click a visible button
await button.ClickAsync("button >> visible=true");
```
