I am working through a Udemy course and have gotten to a module on writing our own version of jQuery. During this module, I created a js file, squery.js. The purpose of this file is to remove the need to use the period symbol to identify classes in the main.js file. I have written both files verbatim to what the instructor was using, but for some reason, I have several errors pop up.

Edit2: Solution at the bottom

I am using the chrome-console and I am trying to output fetched data, and I only get the desired output by writing "await" at exactly the right place, even though another solution can do it earlier and I don't know why/how it works.

solution() is the "official" solution from a web-course I am doing. Both functions return the same, currently. In myFunction I tried writing "await" in front of every used function and make every function "async", but I still can't replace the "await" inside log, even though the other solution can.
