How to create an object based on an interface in TypeScript?

Hi everyone! I started learning TypeScript and ran into a problem. I have an interface describing a user: ```typescript interface User { id: number; name: string; email: string; isActive: boolean; } ``` I want to create an empty object of this type, and then fill its fields as needed. I'm trying to do this: ```typescript const user: User = {}; ``` But TypeScript complains: `Type '{}' is missing the following properties from type 'User': id, name, email, isActive`. I tried writing `const user: User = {} as User;` — this works, but it's unsafe because the fields remain undefined. How to properly create an object based on an interface? Is there a way to do this without explicitly listing all fields? Maybe there are some patterns or TypeScript tricks?
