DayMG)DaysOfJavaScript

一點一點比完美更好不是嗎？

我做了什麼

• 繼續觀看視頻 學習 JavaScript

我學到了什麼

第三天

雙重等於和嚴格等於。

console.log(10 == 10); // True
console.log(10 == "10"); // True
console.log(10 === 10); // True
console.log(10 === "10"); // False

第四天

記得開關。

var hoge;

switch(hoge) {
  case 1:
    console.log("hoge"); // If hoge == 1, output will be "hoge" and "hogehoge"
  case 2:
    console.log("hogehoge"); // If hoge == 2, output will be "hogehoge"
    break;
  case 3:
    console.log("fuga"); // If hoge == 3, output will be "fuga"
    break;
}

第5天

學習對象。

var exampleObject = {
  "hoge": "ほげ",
  "hogehoge": "ほげほげ",
  "fuga": "ふが",
}
/* Dictionary in Python might be similar data structure?
We can add a content with operation like below*/
exampleObject.fugafuga = "ふがふが";
// or...
exampleObject["fugafuga"] = "ふがふが";
// If additional element is same as last element, additional one is ignored.
// (It's just my guess. I've googled but I couldn't find information about it)
