Firefox 25 で Array.prototype.{find, findIndex} が実装された - hogehoge @teramako
[].indexOf に似ているけど、より汎用的なメソッド forEach, map, some, every 等と同様にコールバックを引数にとって、true を返したものの、値またはindex値を返すメソッドである。 実装見たほうが分かりやすいかも。(ちょっと特殊だけどJavaScriptで書かれてるよ！） Array.prototype.find http://mxr.mozilla.org/mozilla-central/source/js/src/builtin/Array.js#395 Array.prototype.findIndex http://mxr.mozilla.org/mozilla-central/source/js/src/builtin/Array.js#433 テストコードは http://mxr.mozilla.org/mozilla-central/so
