@WORMSS Wow, that's pretty neat. A lot of inspiration. I took some ideas and implemented them into uncreate. 🙂

Thank you very much.. Updated Typescript Playground

I actually modified it a little after re-looking at the code yesterday with fresh eyes..
I made it so the headers are merged.. so rather than one or the other.
I also removed the possibility of responseType cobbling, since it was originally calculated after the fetch was returned.

Just small cleanups, nothing major..

I just noticed in your code, that you had arrayBuffer which was a responseType I missed.. so thank you for that.
