### isPrimitive
Returns a boolean determining 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(50); // true
isPrimitive('Hello!'); // true
isPrimitive(false); // true
isPrimitive(Symbol()); // true
isPrimitive([]); // false
```
