尝试将属性从一个对象分配给另一个对象时出现TypeScript错误

interface Person {
  name: string;
  age: number;
}

const person1: Person = { name: "Alice", age: 30 };
const person2: Partial<Person> = { name: "Bob" };

person2 = person1; // Error: Type 'Person' is missing the following properties from type 'Partial<Person>': age

person2 = person1 as Partial<Person>;

interface PartialPerson {
  name?: string;
  age?: number;
}

const person2: PartialPerson = person1; // This works because person1 is assignable to PartialPerson

person2 = { ...person1 }; // This creates a shallow copy and works if person2 is of type Partial<Person>

interface Person {
  name: string;
  age: number;
}

const person1: Person = { name: "Alice", age: 30 };
let person2: Partial<Person> = {};

// Using type assertion
person2 = person1 as Partial<Person>;

// Using type compatibility
interface PartialPerson {
  name?: string;
  age?: number;
}

person2 = person1; // This works because person1 is assignable to PartialPerson

// Using spread operator
person2 = { ...person1 }; // This creates a shallow copy and works if person2 is of type Partial<Person>
