ValueType
I'd like a union of all of the types of the keys in an object. I should do what this describes doing (not sure if this is the best impl) https://www.npmjs.com/package/utility-types#valuestypet
import { ValuesType } from 'utility-types';
type Props = { name: string; age: number; visible: boolean };
// Expect: string | number | boolean
type PropsValues = ValuesType<Props>;
type NumberArray = number[];
// Expect: number
type NumberItems = ValuesType<NumberArray>;
type ReadonlyNumberTuple = readonly [1, 2];
// Expect: 1 | 2
type AnotherNumberUnion = ValuesType<NumberTuple>;
type BinaryArray = Uint8Array;
// Expect: number
type BinaryItems = ValuesType<BinaryArray>;
