Array Iteration

https://gist.github.com/ljharb/58faf1cfcb4e6808f74aae4ef7944cff
While attempting to explain JavaScript's reduce method on arrays, conceptually, I came up with the following - hopefully it's helpful; happy to tweak it if anyone has suggestions.
Intro

JavaScript Arrays have lots of built in methods on their prototype. Some of them mutate - ie, they change the underlying array in-place. Luckily, most of them do not - they instead return an entirely distinct array. Since arrays are conceptually a contiguous list of items, it helps code clarity and maintainability a lot to be able to operate on them in a "functional" way. (I'll also insist on referring to an array as a "list" - although in some languages, List is a native data type, in JS and this post, I'm referring to the concept. Everywhere I use the word "list" you can assume I'm talking about a JS Array) This means, to perform a single operation on the list as a whole ("atomically"), and to return

                Trying to implement bypass CORS Chrome browser policy in a Vanilla JS Binance API small project. Using node-fetch.
              
          
    I've had a really bad time looking for a solution for this. The only thing that I was able to make for for getting the listening key, was adding this extension to my browser https://chrome.google.com/webstore/detail/allow-cors-access-control/lhobafahddgcelffkeicbaginigeejlf/related?hl=es
I came across some other solutions, like some extra dependencies (axios, for example) or running a proxy server (light-server,or lite-server, or some nodejs-proxy-server), but I was not able to make those work in time really.
For what I was able to see, this CORS policy is a big issue for developers. https://www.youtube.com/results?search_query=cors+javascript+fetch
With that extension I was able to get some information about the Request and Response given to/from the server using DevTools from Chrome. Do you think it may be possible to get some information from those headers I can use in my raw code? So I can get rid of that extension. I tried to use some of the key-value pairs I considered to be part of the solution, eve

How can I solve this?
-- 3. How many of each category of bikes do we have in our "Baldwin Bikes" store, which has the store_id of 2.
-- We need to see the name of the category as well as the number of bikes in the category.
-- Sort it by lowest numbers first.
