T의 모든 프로퍼티를 읽기 전용(재할당 불가)으로 바꾸는 내장 제네릭 Readonly<T>를 이를 사용하지 않고 구현하세요.

예시:

ts
interface Todo {
  title: string
  description: string
}

const todo: MyReadonly<Todo> = {
  title: "Hey",
  description: "foobar"
}

todo.title = "Hello" // Error: cannot reassign a readonly property
todo.description = "barFoo" // Error: cannot reassign a readonly property
