TypeScript 型の課題集


















English | 简体中文 | 日本語 | 한국어




## はじめに





TypeScript のチューリング完全な型システムの力で




高品質な型は潜在的なバグを回避しつつ、プロジェクトの保守性を向上させるのに役立ちます。  

TypeScriptには [ts-toolbelt](https://github.com/millsp/ts-toolbelt), [utility-types](https://github.com/piotrwitek/utility-types), [simplytyped](https://github.com/andnp/simplytyped) など優れた型ユーティリティライブラリがあり、私たちは多くの後押しを得ているはずです。



このプロジェクトは、型システムがどのように動作するのかを理解したり、独自の型ユーティリティを書いたり、課題へのチャレンジを楽しむことをサポートします。また、実際の業務で直面した問題を質問したり、その答えを得られるコミュニティを作りたいと考えています。 - そこでの問題が課題集に追加されるかもしれません！
