JavaScript preprocessors can help make authoring JavaScript easier and more convenient. For instance, CoffeeScript can help prevent easy-to-make mistakes and offer a cleaner syntax and Babel can bring ECMAScript 6 features to browsers that only support ECMAScript 5.
Any URL's added here will be added as <script>
s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.
You can apply a script from anywhere on the web to your Pen. Just put a URL to it here and we'll add it, in the order you have them, before the JavaScript in the Pen itself.
If the script you link to has the file extension of a preprocessor, we'll attempt to process it before applying.
You can also link to another Pen here, and we'll pull the JavaScript from that Pen and include it. If it's using a matching preprocessor, we'll combine the code before preprocessing, so you can use the linked Pen as a true dependency.

#引数がなかえればconstructor:()->でOK
#コンストラクタは必ず->を使う
#=>はだめ(@=thisの挙動が異なってしまうため)

#@はES5-6のthis.と同じ意味

#コンストラクタ外では使用できない

#自身のメソッドを実行
#クラスメソッドを実行する場合には、()が必要
#メソッドの実行は常に()が必要だから
@callStart()
#コンストラクタ内で宣言したローカル変数は使える
console.log "local"+ _local
#以下メソッド
callStart: =>
console.log "start: " + @naka + @nishi
#コンストラクタで宣言した_localはコンストラクタの外では使えないのでリファレンスエラーになる

#単にオブジェクトを作る
new Start "a","b"
#作ったものを代入
#変数の宣言時にvar等は宣言してはダメ
start = new Start "b","c"
#メソッドを実行
start.log();
