Typescript:从泛型对象中删除键

interface MyObject {
  key1: string;
  key2: number;
  key3: boolean;
}

function deleteKey(obj: MyObject, key: keyof MyObject): MyObject {
  const { [key]: deleted, ...rest } = obj;
  return rest;
}

const obj: MyObject = {
  key1: "value1",
  key2: 123,
  key3: true,
};

const newObj = deleteKey(obj, "key2");
console.log(newObj); // { key1: "value1", key3: true }

interface MyObject {
  key1: string;
  key2: number;
  key3: boolean;
}

type Omit<T, K extends keyof T> = Pick<T, Exclude<keyof T, K>>;

function deleteKey<T extends object, K extends keyof T>(obj: T, key: K): Omit<T, K> {
  const { [key]: deleted, ...rest } = obj;
  return rest;
}

const obj: MyObject = {
  key1: "value1",
  key2: 123,
  key3: true,
};

const newObj = deleteKey(obj, "key2");
console.log(newObj); // { key1: "value1", key3: true }
