# JsObject.fromBrowserObject constructor

JsObject.fromBrowserObject(dynamic object)

Constructs a JsObject that proxies a native Dart object; for expert use only.

Use this constructor only if you wish to get access to JavaScript properties attached to a browser host object, such as a Node or Blob, that is normally automatically converted into a native Dart object.

An exception will be thrown if `object` either is `null` or has the type `bool`, `num`, or `String`.

## Implementation

    factory JsObject.fromBrowserObject(object) {
      if (object is num || object is String || object is bool || object == null) {
        throw new ArgumentError("object cannot be a num, string, bool, or null");
      }
      return _wrapToDart(_convertToJS(object));
    }
