+* Returns: {boolean}
+
+Returns `true` if the value is any boxed primitive object, e.g. created
+by `new Boolean()`, `new String()` or `Object(Symbol())`.
+
+For example:
+
+```js
+util.types.isBoxedPrimitive(false); // Returns false
+util.types.isBoxedPrimitive(new Boolean(false)); // Returns true
+util.types.isBoxedPrimitive(Symbol('foo')); // Returns false
+util.types.isBoxedPrimitive(Object(Symbol('foo'))); // Returns true
+util.types.isBoxedPrimitive(Object(BigInt(5))); // Returns true
