在Typescript中,是否可以创建一个泛型类型,根据给定类型的类型从中删除键

这个 Pick type包含在TypeScript中。具体实现如下:

type Pick<T, K extends keyof T> = {
  [P in K]: T[P];
};

你会怎么写 PickByValue 键入以下内容:

type Test = {
  includeMe: 'a' as 'a',
  andMe: 'a' as 'a',
  butNotMe: 'b' as 'b',
  orMe: 'b' as 'b'
};

type IncludedKeys = keyof PickByValue<Test, 'a'>;
// IncludedKeys = 'includeMe' | 'andMe'
