Fill in the blank to add the language2 property to the child class. class AfricanNation extends Nation {

Fill in the blanks to include two properties from the parent class and add the language2 property to the child class. class AfricanNation extends Nation {

this.language2 = language2;		 super\(name,language\);[\r\n]this\.language2=language2;
Fill in the blanks to include the name and language properties from the parent class and add the language2 property to the child class. class AfricanNation extends Nation {

}		   constructor(name, language, language2) {

    this.language2 = language2;		 constructor\(name,language,language2\){[\r\n]super\(name,language\);[\r\n]this\.language2=language2;
Copy a single property from a parent class to a child class and add one property that's unique to the child class. Make up everything. class AfricanNation extends Nation {
  constructor(name, language) {
    super(name);
    this.language = language;
  }
}		 class[A-Z][a-zA-Z0-9_$]*extends[A-Z][a-zA-Z0-9_$]*{[\r\n]constructor\(([a-z_$][a-zA-Z0-9_$]*),([a-z_$][a-zA-Z0-9_$]*)\){[\r\n]super\(\1\);[\r\n]this\.\2=\2;[\r\n]}[\r\n]}
Copy a single property from a parent class to a child class and add one method that's unique to the child class. The method does nothing. Make up everything. class AfricanNation extends Nation {
  constructor(name) {
    super(name);
  }
  doNothing() {
  }
}		 class[A-Z][a-zA-Z0-9_$]*extends[A-Z][a-zA-Z0-9_$]*{[\r\n]constructor\(([a-z_$][a-zA-Z0-9_$]*)\){[\r\n]super\(\1\);[\r\n]}[\r\n][a-z_$][a-zA-Z0-9_$]*\(\){[\r\n]}[\r\n]}
Copy a single property from a parent class to a child class and add one method that's unique to the child class. The method displays the value of the property in the console. Make up everything. class AfricanNation extends Nation {
  constructor(name) {
    super(name);
  }
  showValue() {
    console.log(this.name);
  }
}		 class[A-Z][a-zA-Z0-9_$]*extends[A-Z][a-zA-Z0-9_$]*{[\r\n]constructor\(([a-z_$][a-zA-Z0-9_$]*)\){[\r\n]super\(\1\);[\r\n]}[\r\n][a-z_$][a-zA-Z0-9_$]*\(\){[\r\n]console\.log\(this\.\1\);[\r\n]}[\r\n]}
  1. I've coded a class. Build on this class to create a new class.
  2. Add a property to the new class.
  3. Use the child class to create a new object.
  4. Display the value of the added property in an alert.
  5. Wait a moment.
  6. If you've coded correctly, an alert will display the property value.
  7. Dismiss the alert by clicking OK.
  8. For help with this code, see Chapter in the book.
