まだ個人的な気持ちでしかないんだけどメモ。
TypeScriptでResult型でのエラーハンドリングを通してモナドの世界を覗いてみる #関数型プログラミング - Qiita
より。
内容はとてもよいと思うんだけど、やはり
export const ok = (value: T): Ok => ({ ok: true, value });

- 自分たちの書いたJSのコードのみのエラーを監視する方法は？
- ぶっちゃけ Reactivity が嬉しいシーンてそんなに多いの？
- 単にツールが有名で強力なものに揃っている方が採用、育成も含めて有利ってだけ？
- VirtualDOM のデメリットは？
- TypeScript 導入するとぶっちゃけコード書くの早くなる？遅くなる？
- type の定義方法に決まりはある？
- JSX って本当によい？ tagged literal
html``で十分では？ - CSS はもう素朴に custom property と簡単な Scss 程度でよくない？
- UI の開発に本当に大事なのはツールよりユーザーのゴールと状態の設計では？
