# init(object:in:)

Creates a JavaScript value by converting the specified native object.

## Declaration

```swift
init!(object value: Any!, in context: JSContext!)
```

## Parameters

- `value`: The Objective-C or Swift object to be made available to JavaScript.
- `context`: The JavaScript context in which to create the value.

## Return Value

Return Value A new JavaScript value representing the object.

## Discussion

Discussion Converting a native object creates a JavaScript object, including a constructor and prototype chain that reflects the object’s inheritance in the Objective-C or Swift type hierarchy. By default, properties and methods on the converted object are not exposed to JavaScript: to choose which properties and methods should be visible to JavaScript, see JSExport. Creating a JSValue instance that wraps a native object retains the underlying Objective-C or Swift object.
