It's not too bad to learn a little JS in back end.

More complex than, for example, the introduction to Python, but with time you can progress, until you reach the point of downloading and using the cmd environment. If you haven't done Linux before, it's highly complex.

For me, this was actually easier to grasp than the python course. I had to look some things up in the documentation that's provided when I was stuck, but in general this was very accessible, and I often struggle with coding.

I think I wish this had a bit more on async/await but a good course.

The course asked me to throw an error in chapter 5 before it taught me how errors work in JavaScript as that isn't thought until chapter 9. Other than that it was great.
