Overall, you did an awesome job. I know this material can be difficult - just let me know if you need extra understanding! Something I would recommend is for you to review the lecture videos. There is a lot to learn the second time around! Upon saying that, if you get stuck on anything for more than 20 min, HOLLER AT SOMEONE. ❤️

| 1. .forEach merely iterates through an array while .map actually iterates and takes the elements to make a new array. |

A clear difference is that forEach doesn't return anything whereas map does! Good answer!

| 2. Boolean, Null, Undefined, Number, String, Symbol and Object. An array is an object but it comes with tons of methods (like .length) that can be used to iterate through it. | ||

| 3. Closures are functions called within themselves that can store the updated variables of their outer scoped function. |

Your definition of closures is 100% correct! I forgot to give you a link to understand it more in-depth but better late than never right?? 😅

You should have it so that it returns ++count . When you have count++ it will save the count before it iterates which is something that we don't want!

This method can be done by looking at your previous projects! Take a look at JS-II I believe.
For this portion, you can implement something like a counter and calling a cb from it. If you are still having trouble, just let me know or your group!
