# var xs = [1,2,3]
# doubleMe(doubleMe(doubleMe(xs)))
#這樣寫法有很多缺點，太多層次要把全部層次讀完才能知道最後結果。

#在墮性語言之中
#我們要做到調用 doubleMe 時並不會立即求值，它會說“嗯嗯，待會兒再做！”
#在真正執行時只會是一個平面，像 xs *2 *2 *2;

(a, b, c) --> a * b * c
#代替了

Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).
