Creating a Type in Typescript that Inherits Keys from Another Type

Imagine you're faced with this scenario involving a Typescript class:

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

If you were to create an object type with the same properties, using the any type, but with all properties being optional - how would you approach it? Consider these possible values that should align with the requested type:

data = {};
data = {name: 'John'};
data = {name: anyValue};
data = {age: 'can be a string'}
data = {name: anyValue, age: null};

Faced with this challenge, you might feel unsure of your path forward. I've attempted something along these lines myself:

let data: {(keyof Person): any};

However, as it turns out, that codes does not compile as expected.

Answer №1

You're getting close with your latest attempt!

const info: { [key in keyof Person]: any };
