Why use Redux over Facebook Flux?
I've read this answer, reducing boilerplate, looked at few GitHub examples and even tried redux a little bit (todo apps).

(see No Streaming Unzip API). Don't block the JavaScript thread. Use and provide async APIs. Keep memory usage under control. Don't attempt to buffer entire files in RAM at once. Never crash (if used properly). Don't let mal
漢字にマッチする JavaScript の正規表現パターン: Days on the Moon
たまに漢字にマッチする正規表現パターンを書きたいときがあります。Perl の正規表現だと Unicode のスクリプト名を使って \p{Han} で漢字にマッチさせられるのですが、JavaScript ではそうはいきません。JavaScript の正規表現には以下のふたつの問題があります。 Unicode スクリプト名の指定 (\p{...}) に対応していない。 そもそも Unicode の符号位置に対してマッチさせられない (UTF-16 における符号単位に対するマッチになる)。 BMP 外の文字にマッチさせたいときは、サロゲートペアの符号単位を記述する必要がある。 これに関しては ECMAScript 2015 で導入された /u フラグで解決する見込み。 とはいえ、解決不能な問題というわけでもないので、Perl の \p{Han} を JavaScript に移植してみましょう。\
