Take the argument destructuring challenge

const quiz1 = ({ a, b = 2 }) => b;
const quiz2 = ({ a, b = 2 } = {}) => b;
const quiz3 = ({ a, b = 2 } = { b: 3 }) => b;
const quiz4 = ({ a, b } = { b: 3 }) => b;
const quiz5 = ({ a, b }) => b;

	quiz1	quiz2	quiz3	quiz4	quiz5
quiz()	?	?	?	?	?
quiz({})	?	?	?	?	?
quiz({ a: 1 })	?	?	?	?	?
quiz(null)	?	?	?	?	?

[copy and paste this below]

|                  | `quiz1` | `quiz2` | `quiz3` | `quiz4` | `quiz5` |
| -                | -       | -       | -       | -       | -       |
| `quiz()`         | ?       | ?       | ?       | ?       | ?       |
| `quiz({})`       | ?       | ?       | ?       | ?       | ?       |
| `quiz({ a: 1 })` | ?       | ?       | ?       | ?       | ?       |
| `quiz(null)`     | ?       | ?       | ?       | ?       | ?       |
