+Checks if the passed value is primitive or not.
+
+- Create an object from `val` and compare it with `val` to determine if the passed value is primitive (i.e. not equal to the created object).
+
+```js
+const isPrimitive = val => Object(val) !== val;
+```
+
+```js
+isPrimitive(null); // true
+isPrimitive(undefined); // true
+isPrimitive(50); // true
+isPrimitive('Hello!'); // true
+isPrimitive(false); // true
+isPrimitive(Symbol()); // true
+isPrimitive([]); // false
+isPrimitive({}); // false
+```
