hello "john"   => "Hello, John!"
hello "aliCE"  => "Hello, Alice!"
hello          => "Hello, World!" # name not given
hello ''       => "Hello, World!" # name is an empty String
*/

function hello(name="World!") {
return name===''||name==="World!"?'Hello, World!':`Hello, ${name[0].toUpperCase()+name.slice(-name.length+1).toLowerCase()}!`;
}
