TypeScript function to set value by key

While researching React stores automation, I wondered whether it would be possible to have a TypeScript function to set the value of an object by the name of its property, with correctly typed parameters, of course.

Turns out, it is

export function setField<
	T extends object,
	K extends keyof T,
>(o: T, k: K, v: T[K]): void {
	o[k] = v;
}

The function above works perfectly with interfaces:

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

const p: Person = { name: 'Joe', age: 42 };
setField(p, 'name', 'foo');
