At this point, you should feel pretty good idea about working with functions. So naturally, I have a challenge with you. In this episode, you’re going to get three challenges. So let’s get started.

String youAreWonderful
String youAreWonderful(String name) {

}
return 'You are wonderful, $name';
print(youAreWonderful('Douglas'));
String youAreWonderful(String name, int numberOfPeople) {
return 'You are wonderful, $name. $numberOfPeople people think so.';
print(youAreWonderful('Douglas', 10));
String youAreWonderful({ String name, int numberOfPeople } ) 
String youAreWonderful({ required String name, int numberOfPeople } ) 
String youAreWonderful({ required String name, int numberOfPeople = 30} ) 
print(youAreWonderful(name: 'Douglas', numberOfPeople: 10));
print(youAreWonderful(name: 'Jeremy'));
