Fetch is great. I never understood the need for installing axios when fetch works fine. I remember the good old days of XMLHttpRequest.

Axios has better errror handling.

Fetch doesn't have progress bars yet.

False, you can use response.body which is a ReadableStream. See https://fetch-progress-demo.glitch.me/ for a simple example.

I think the point wasn't that jquery was old, but it was way too new for the rest of the page. Everything on it screams mid 90s, and then jquery which is a good 10 years later.
