Async Await Is The Worst Thing To Happen To Programming
It’s so good. It captures exactly how I feel about async and await. If you wait for async code your function now has to be async as well. And if there’s any function relying on that function that code also has to be async and on and on and on. Until you reach the top level.
I’ve always hated this. But there’s no better way to do this. It’s a necessary evil. Right..? Well, I’ve recently been coding a lot in Go. And Go does not have async and await. And this is despite it being famous for its concurrency. And you know what? I really like it.

So I decided to add a one second delay between requests. How do you do this? It’s as simple as:
