	Returns the string that the value represents if it does, otherwise it should not be called.

bool	isString () const
	Indicates if the given value represents a string.

	Returns the number that the value represents if it does, otherwise it should not be called.

bool	isNumber () const
	Indicates if the given value represents a number.

bool	asBool () const
	Returns the boolean that the value represents if it does, otherwise it should not be called.

bool	isBool () const
	Indicates if the given value represents a boolean.

std::shared_ptr< JsObject >	asJsObject () const
	Returns a `JsObject` if the value represents a boolean value.

std::shared_ptr< JsProxyObject >	asJsProxyObject () const
	Returns a `JsProxyObject` if the value represents a boolean value.

	Constructs a JavaScript value from the convertible C++ one.

Detailed Description

A JavaScript value.

This class stores C++ values that are convertible to JavaScript ones.

The type mapping rules are the following:

C++	JavaScript
double	Double
std::string	String
bool	Boolean
std::shared_ptr<SomeJsObject>	Object
std::shared_ptr<JsArray>	Array
std::shared_ptr<SomeJsProxyObject>	Proxy Object

where

Other types cannot be automatically converted to JavaScript values, and first must be converted to one of the types above.
