I’m gett the ing UDP same vib joke
It’s funny but the random capitalization is distracting
it’s not that random, it’s the original text

I PROMISE the rest will come eventually
that is going to take some RESOLVE
You must
.awaitbefore you can have theResult. Then you can use?
I’m actually laughing out loud at the amount of whitespace because
threadroutine is still executing lmaoFor those who don’t get it, it’s the “stop doing science” meme.
less async more nsync
Honestly, I don’t get it.
Is it about the syntax sugar? Would you like to use callbacks instead?
Async programming is when you achive concurrency even with one thread. It’s needed. There’s no alternative to this.
It’s a meme, it’s not actually saying not to use async:
I honestly don’t know, why async got so popular. It seems like the entire reason for doing it was that some blokes were hellbent on using JS on a server and couldn’t fathom that a second thread might be a good idea.
A huge amount of time in apps is spent waiting for IO, database or web requests to complete.
Async prevents locking a thread during this wait.
If you’re handling a large amount of requests in a web server, for example, it allows other requests to progress while waiting for these operations.
Threads are also expensive to start and manage.
Also handling threads manually is a pain in the ass.
Async is good because threads are expensive, might aswell do something else when you need to wait for something anyways.
But only having async and no other thread when you need some computation is obviously awful… (or when starting anothe rthread is not easily manageable)Thats why i like go, you just tell it you want to run something in parallel and he will manage the rest… computational work, shift current work to new thread… just waiting for IO, async.
Async rust with the Tokio Framework is pretty cool. Need none of that JS bloat for async.
Async Rust sucks. I hate how many libraries use it, forcing it apon you.
You suck, I hate how your comment was forced “apon” me. Anyone who claims things that they can easily avoid if theyre so opinionated against them are “forced upon” them are always pathetic people.
If you are waiting for IO, why would you block your current thread and not let it do something else? Async does not only exist in JS.
Ok, I’m a c# developer and I use async await quite extensively. Is it different in JS? Or am I missing something?
Nah, they’re very similar, really. You generally kick IO heavy stuff you don’t need immediately off to async await.
There are a few more applications of it in C# since you don’t have the “single thread” to work with like in JS. And the actual implementation under the hood is different, sure. But conceptually they’re similar. Pretty sure JS was heavily influenced by C#'s implementation and syntax.
async/await is just
callback()andqueueMicrotaskwrapped up into a neat package. It’s not supposed to replace multi-threading and confusing it for such is dangerous since you can still stall your main/UI thread with Promises (which async also wraps).(
asyncandawaitare also technically different things, but for the sake of simplicity here, consider them a pair.)Because the alternative is a series of ridiculously nested call backs that make code hard to read and manage?
I honestly can’t fathom how anyone would dislike async programming.
After using both extensively I would argue async code is easier to read. It has a lot less nesting. And generally easier to read code is a good thing so I’m all for async.
