Returns the value associated with the specified key or an empty Optional if there is no such key in this map.

The type mapping rules are the following:

| JavaScript         | Java           |
|--------------------|----------------|
| Number             | Double         |
| String             | String         |
| Boolean            | Boolean        |
| null and undefined | null           |
| Node               | JsObject, Node |
| ArrayBuffer        | JsArrayBuffer  |
| Array              | JsArray        |
| Set                | JsSet          |
| Map                | JsMap          |
| Object             | JsObject       |
| Proxy Object       | Object         |

For proxy objects, the corresponding injected Java object is returned.
