+
+Get the union type of all the values in an object, tuple, array or array-like type `T`.
+
+**Usage:**
+
+```ts
+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>;
+```
