Define a method hello that returns "Hello, Name!" to a given name, or says Hello, World! if name is not given (or passed as an empty String).

	Assuming that name is a String and it checks for user typos to return a name with a first capital letter (Xxxx).
	
	Examples:
				

	* With `name` = "john"  => return "Hello, John!"
	* With `name` = "aliCE" => return "Hello, Alice!"
	* With `name` not given 
	or `name` = ""        => return "Hello, World!"				

Solution by -

	function hello(name) {
		return name == "" || !name ? "Hello, World!" : "Hello, " + name.charAt(0).toUpperCase() + name.toLowerCase().substring(1) + "!";
		}
