Property does not exist on type {}?

Question

typescript

When initializing the function, there is an empty object user = {}
Then I get the user and assign it to a variable.
Further, when I try to access its fields, for example user.name, I get an error ts -

Property 'name' does not exist on type {}

How can I get rid of this other than setting all fields initially as name: ''?

Answer 1

interface User {
  name?: string;
}

let user: User = {};

or

interface User {
  name: string;
}

let user = {} as User;
