# construct(withArguments:)

Invokes the value as a JavaScript constructor.

```
func construct(withArguments arguments: [Any]!) -> JSValue!
```

## Parameters

`arguments`

The parameters to pass to the constructor. The objects in this array must be other [`JSValue`](/documentation/JavaScriptCore/JSValue) objects or objects that can be converted to JavaScript values using the methods listed in Creating JavaScript Values.

## Return Value

The result of calling the value as a constructor, or `nil` if the value cannot be treated as a JavaScript constructor.

## Discussion

Calling a constructor is equivalent to using the `new` keyword in JavaScript.
