`JSONValue` | `get(int index)` Returns the value at the specified index position.
`JavaScriptObject` | `getJavaScriptObject()` Returns the underlying JavaScript array that this object wraps.
`(package private) JavaScriptObject` | `getUnwrapper()` Internal.
`int` | `hashCode()`
`JSONArray` | `isArray()` Returns `this`, as this is a JSONArray.
`JSONValue` | `set(int index, JSONValue value)` Sets the specified index to the given value.
`int` | `size()` Returns the number of elements in this array.

  Returns the underlying JavaScript array that this object wraps.

### hashCode

    public int hashCode()

  Overrides:
    `hashCode` in class `java.lang.Object`

### isArray

    public JSONArray isArray()

  Returns `this`, as this is a JSONArray.

    size of this array

### toString

    public java.lang.String toString()

  Create the JSON encoded string representation of this JSONArray instance. This method may take a long time to execute if the underlying array is large.

  Specified by:
    `toString` in class `JSONValue`

### getUnwrapper

    JavaScriptObject getUnwrapper()
