米Yahoo!がYUI新規開発中止を発表。その背景となったJavaScriptの現状解説
米Yahoo!のエンジニアリングチームは、同社がこれまでJavaScriptライブラリとして開発してきたYahoo User Interface library（YUI）の新規開発を中止すると発表しました。 YUIは、JavaScriptでインタラクティブなWebサイトを構築する技術「Ajax」への注目が高まっていた2009年に登場したライブラリです。さまざまなメニュー、カレンダーやカラーピッカー、タブ、リッチテキストエディタなどのコンポーネントが揃っているだけでなく、DOM操作やイベントハンドリング、テスト用ライブラリやJavaScript圧縮ツールなど、幅広くJavaScriptを強化するための機能を備えています。 しかしその後登場したjQueryなどのさまざまなライブラリやツールに人気を奪われ、ここ数年はYUIへの注目度も低下。コミュニティからのリクエストも少数になり、多くのモジュー
