var students = new Array(
    "tellies",
    "amaris",
    "ashley"
);
// 鼓勵直接用 [] 來寫
students.length; // 3
students.push("joseph"); // tellies,amaris,ashley
students.shift(); // amaris,ashley,joseph
students.pop(); // amaris,ashley
students.splice(1, 0, "alen", "knock"); // amaris,alen,knock,ashley
students.splice(2, 1, "gary"); // amaris,alen,gary,ashley
var str = students.join(" + "); // amaris + alen + gary + ashley
