1. let myAge = 19;
   
2. let earlyYears = 2;
   
3. earlyYears *= 10.5; // 前兩年等於 2 x 10.5 歲
   
4. let laterYears = myAge - 2;
   
5. laterYears *= 4; // 之後的年紀 x4 歲
   
6. console.log(earlyYears);
   
7. console.log(laterYears);
   
8. let myAgeInDogYears = earlyYears + laterYears;
   
9. let myName = "POPO".toLowerCase();
