Overall things are looking pretty good. I would suggest coming back and plowing through the extra credit. Also there are many line breaks where there don't need to be, and as for me, (this being a stylistic preference) I would return the PR and ask you to fix those line breaks. But that's not the case for everyone's style. Overall you're doing great. Keep it up. Keep plowing through the complicated stuff! It's not easy!

You're good to reuse your .each() method here. Maybe you could give it a try.

Nice default in the parens.

Not sure what's going on with two different loops here. There may be a better way to solve this. Please refer to the video posted about flatten and reduce, it's up in Week 1 on your piazza account.

This all looks really good. It seems like you have a good grasp on these concepts here.

No need for this space right here.

Nice work. I really like indexOf. And I like that you used an array to cache your function call. I would rename this array to something more descriptive other than 'arg' just to make sure if someone was to re-read your code, they'd be able to understand exactly what 'arg' is.

You can just deleted code that you've commented out. It makes for a cleaner submission.
| // Return `obj`. | ||

| function hasKey(o, ky) { | ||
| // const objKeys = Object.keys(o); |

please remove this commented out code

| // return the nth number in the sequence | ||

I think you can simplify all of this logic to one single line. if (n <= 2) return n
| }); | ||
| // console.log(`Check: No object found in values. (@ depth level:${level})`); | ||
| return true; | ||

You're going to be receiving this as a toy problem today. You should be able to think through it. Otherwise you'll have some exposure to it and you'll be able to come back and nail it!
First set of complete answers.
