I would love to go over arrays-- that tripped me up both in the readings and in the assignment!

I'd be happy to. Arrays are a sequence of values, indexed by their location in the array.


    let kids = ["Ross", "Charlotte"];
    console.log("First kid is ", kids[0]);
    let bigKids = kids.map((k) => k.toUpperCase());
    bigKids.forEach((kid, index) => { console.log(index, ": ", kid) });

I am still a bit confused about the difference between forEach and map / I'm confused about the forEach method. How is it different from a loop?

Great question. For map:

map takes a function of one argument
map invokes that function on every array element
map collects all the return values from that function
map returns a new array with all the return values

While forEach:

forEach takes a function of one, two or three arguments.
forEach invokes that function on every array element, its index, and the array
forEach returns no value

Yeah, forEach takes the place of a loop. The difference is that is a method rather than a syntactic construct.
