Question

Implement the built-in Pick<T, K> generic without using it.
Constructs a type by picking the set of properties K from T
For example

interface Todo {   
    title: string   
  description: string   
  completed: boolean 
} 
type TodoPreview = MyPick<Todo, 'title' | 'completed'> 
const todo: TodoPreview = {     
  title: 'Clean room',     
  completed: false, 
}

Answer

type MyPick<T, K extends keyof T> = {
  [P in K]: T[P]
}
