var personArray = [];
personArray.push(new person("LiKe",18))
personArray.push(new person("LiKe1",118))
personArray.push(new person("LiKe2",128))
personArray.push(new person("LiKe3",8))
personArray.push(new person("LiKe4",81))
function compareAge(a,b){
return a.Age-b.Age;
}
personArray.sort(compareAge);
console.log(personArray);`
