Sorry guys but in the video Combining filter() and reduce() I actually have more questions than answers.

I don't understand how the reduce method has worked in this video. Layman terms please if someone has time. Thank you in advance.

Came here to say the same! I took a break from this section yesterday bc it was becoming a lot. Today I was understanding the first few concepts, then arrived here and I am completely lost.

I suppose what I understand the least, is how in the example, it new to compare the "highest" value. Same with the sum. If these are variables we are supplying, then how do they know what to do? I understand comparison operators are involved ('>', '+'), I guess I am just missing the link between how they are working here!
