Rewrite the following code using ES2015(ES6) syntax.

Question

Either the following code:

```javascript
function Creature(name, age, strength) {
  this.name = name;
  this.age = age;
  this.strength = strength;
}

Creature.prototype.saySomething = function(words) {
  console.info(this.name + 'says:' + words.toLowerCase());
}

function Orc(name, age, strength) {
  Creature.call(this, name, age, strength);
}

Orc.prototype = Object.create(Creature.prototype, { constructor: { value: Orc }});

Orc.prototype.scream = function(words) {
  console.info(this.name + 'screams:' + words.toUpperCase() + '!!!');
}
```

How could we use the ES2015(ES6) syntax to improve this code so that it gives **exactly** the same result?

Accepted Answer

```javascript
class Creature {
    constructor(name, age, strength) {
        this.name = name;
        this.age = age;
        this.strength = strength;
    }
    saySomething(words) {
        console.info(this.name + 'says:' + words.toLowerCase());
    }
}

class Orc extends Creature {
    constructor(name, age, strength) {
        super(name, age, strength);
    }
    scream(words) {
          console.info(this.name + 'screams:' + words.toUpperCase() + '!!!');
    }
}
```

Answer

```javascript
class Creature {
    __construct(name, age, strength) {
        this.name = name;
        this.age = age;
        this.strength = strength;
    }
    saySomething(words) {
        console.info(this.name+ 'says:'+ words.toLowerCase());
    }
}

class Orc implements Creature {
    __construct(name, age, strength) {
        super(name, age, strength);
    }
    scream(words) {
          console.info(this.name + 'screams:' + words.toUpperCase() + '!!!');
    }
}
```

Answer

```javascript
class Creature {
    this.name = name;
    this.age = age;
    this.strength = strength;

function saySomething(words) {
        console.info(this.name + 'says:' + words.toLowerCase());
    }
}

class Orc extends Creature {
    super(name, age, strength);

function scream(words) {
          console.info(this.name + 'screams:' + words.toUpperCase() + '!!!');
    }
}
```

Answer

```javascript

    }
    saySomething(words) {
        console.info(this.name + 'says:' + words.toLowerCase());
    }
}

class Orc extends Creature {
    constructor(name, age, strength) {
        Creature(name, age, strength);
    }
    scream(words) {
