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).

Pattern Matching

This is a strawman proposal for adding pattern matching to ECMAScript. Pattern matching is useful for matching a value to some structure in a similar way to destructuring. The primary difference between destructuring and pattern matching are the use cases involved - destructuring is useful for binding pieces out of larger structures whereas pattern matching is useful for mapping a value's structure to data or a set of behaviors. In practice this means that destructuring tends to allow many shapes of data and will do its best to bind something out of it, whereas pattern matching will tend to be more conservative.

Additionally, the power of pattern matching is increased substantially when values are allowed to participate in the pattern matching semantics as a matcher as well as a matchee. This proposal includes the notion of a pattern matching protocol - a symbol method that can be implemented by objects that enables developers to use those values in pattern matching. A common scenario w

@kangax's ES6 quiz, explained

@kangax created a new interesting quiz, this time devoted to ES6 (aka ES2015). I found this quiz very interesting and quite hard (made myself 3 mistakes on first pass).

Here we go with the explanations:

Question 1:

(function(x, f = () =&gt; x) {

$ brew update
$ brew tap caskroom/cask
$ brew install Caskroom/cask/java

And Java 8 will be installed at /Library/Java/JavaVirtualMachines/jdk1.8.xxx.jdk/

Check version:
