			A [Variant] containing the parsed JSON. Use typeof() to check if it is what you expect. For example, if JSON source starts with braces [code]{}[/code] a [Dictionary] will be returned, if JSON source starts with array braces [code][][/code] an [Array] will be returned.
			[i]Be aware that the JSON specification does not define integer or float types, but only a number type. Therefore, parsing a JSON text will convert all numerical values to float types.[/i]
