TypeScript の型定義メモ

https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/react-router/index.d.ts

export function useParams<Params extends { [K in keyof Params]?: string } = {}>(): { [p in keyof Params]: keyof Params[p] extends undefined ? string | undefined : string };

`<Params extends { [K in keyof Params]?: string } = {}>`

ジェネリック型パラメーター宣言
key は Params のプロパティ名、value は string

rails new した時の --skip-test と --skip-system-test の違い

--skip-test と --skip-system-test をそれぞれつける時とつけない時で比較した

$ diff -ru nooption skiptest

$ diff -ru nooption skipsystemtest
