Inconsistency with Assign docs

[ofekisr]

Description

from the README

import { Assign } from 'utility-types';

type Props = { name: string; age: number; visible: boolean };
type NewProps = { age: string; other: string };

// Expect: { name: string; age: string; visible: boolean; other: string; }
type ExtendedProps = Assign<Props, NewProps>;

age type value in expect is string

from src/mapped-types.ts

/**
 * Assign
 * @desc From `U` assign properties to `T` (just like object assign)
 * @example
 *   type Props = { name: string; age: number; visible: boolean };
 *   type NewProps = { age: string; other: string };
 *
 *   // Expect: { name: string; age: number; visible: boolean; other: string; }
 *   type ExtendedProps = Assign<Props, NewProps>;
 */

age type value in expect is number
