2015/08/22 グランフロントエンド asm.jsとWebAssemblyって実際なんなの？ おのうえ (@_likr) !4

フリーランチの終焉 ✤ フロントエンド開発への要求は⾼まる ✤ ハードウェア、JSエンジンの性能向上の恩恵を知らな いうちに受けていた時代は終わるかもしれない？ ✤ フロントエンドエンジニア(JSプログラマ)が
 JavaScriptプログラムの速度に負う責任が増す !5

まとめ ✤ asm.jsを効果的に使えば、これまでWebでできなかっ た種類のアプリケーションが実現できる ✤ WebAssemblyによる順当な進化に期待 ✤ なんでも速くなる魔法ではないので、
 ⽤法⽤量を守って正しくお使いください !6

プログラミング⾔言語Rust おのうえ@_likr Grand Frontend Osaka 2016 2016年年8⽉月27⽇日

まとめ • Rustはいいぞ • WebAssemblyの実装は着実に進んでいる • RustでWebの部品を作れる未来はそう遠くない（かも • 未来に備えよう • たまにはWebの未来を考えてみるのはいかが？
