/**
 * <p>

 * {@code JSObject} instance is passed to the JavaScript engine,
 * it is unwrapped back to its original JavaScript object. The
 * {@code JSObject} class provides a way to invoke JavaScript
 * methods and examine JavaScript properties.

 * converted to Java data types. Certain data passed to the JavaScript
 * engine is converted to JavaScript data types.
