Which is More Mysterious: The Origins of the Universe or Axios?

I’ve decided Axios is the most mysterious thing on planet Earth or perhaps in the entire universe. More mysterious than sasquatch. More mysterious than Area 51. More mysterious than the breeding habits of Great White Sharks. I can’t find any documentation or info about syntax or what a “Promise-based Http Client” is or does that doesn’t casually use the phrase “promise-based” in the answer like a “promise-based client” is something we all learned way back in the day, like how to tie our shoes or wipe our own ass. Its ludicrous and clearly is driving me insane. It feels like everyone was just born knowing Axios.
