从 JSON 对象中选择值，其中 Typescript 类型的键

Question

I have a the following type:

interface User {
  email: string;
  name: string;
}

...and the following react component:

const MyComponent = <Values extends object>({ values }: { values: Values }) => {
  console.log(values);
  return <div></div>
}

Let's say I use MyComponent with the User interface, and so I'm able to pass values to it. The question is: how do I modify the values JSON object being passed to pluck out any properties in it that are not present in the generic type Values ? In other words, if I pass the object:

{
  email: 'mail@example.org',
  name: 'Some name',
  foo: 'bar'
}

I need the console.log(values) in the component to log the object without foo: 'bar' in it.

类型在运行时不存在 Typescript编译为 javascript。
