Morris' Blog 我在摸索我存在的意義、生命的意義、內涵及價值。 沒有真正神手般的厲害，套用模式是大部分的情況。 沒那麼厲害的我存在的意義為何，襯托出神的存在？ 有時候不能怪別人不給我機會，我已經開始省思， 為什麼我沒有給別人機會的原因，而是全要靠別人。 有時候我認為我與眾不同，那是因為我做不到很多人能辦到的事情。 我聽不到、玩不起來、說得不夠明瞭、理解得不夠多， 我缺少的語文能力，就是一切一切無能的判定。 為此，我不曉得能做些對別人有幫助的事情。 我知道我自己是個不服輸的性格，但現在我不得不認輸。 我沒有能力，因此我必須認輸。 我到底來這世界作什麼？處處充滿不確定性， 而我總是無法出類拔萃，想當個一般人似乎也回不了頭了。 越強大的挑戰需要越強力的支持，而我的支持是什麼？ 最近嘗試與人談話，但都是失敗的結局，沒人能接受， 不需要言語，不需要溝通，一切所想都表達不出來。

Objects, Objects Everywhere

// complete these definitions so that they will have
// the appropriate types
var anObj = { job: "I'm an object!" };
var aNumber = 42;
var aString = "I'm a string!";

console.log(typeof(anObj)); // should print "object"
console.log(typeof(aNumber)); // should print "number"
console.log(typeof(aString)); // should print "string"

var myObj = {
    // finish myObj
    name: "Morris",
};

console.log( myObj.hasOwnProperty('name') ); // should print true
console.log( myObj.hasOwnProperty('nickname') ); // should print false

You Down With OOP?

function Dog (breed) {

};

// here we make buddy and teach him how to bark
var buddy = new Dog("golden Retriever");
Dog.prototype.bark = function() {

};
buddy.bark();

// here we make snoopy
var snoopy = new Dog("Beagle");
/// this time it works!
snoopy.bark();

var gary = new Cat("Gary", "Domestic Shorthair");

// add a method "meow" to the Cat class that will allow
Cat.prototype.meow = function() {

// all cats to print "Meow!" to the console

// provided code to test above constructor and method
var penguin = new Penguin("Captain Cook", 2);
penguin.sayName();

function Penguin(name) {

}
Emperor.prototype = new Penguin();

// create an "emperor" object and print the number of legs it has
var emperor = new Emperor("ee");
