my poo poo's more python, lua, and a tiny amount of bash tbh
could probably give it a shot though

alright, newbie, *tucks icon away*, in order to truly be welcomed to this forum in which i am definitely an OG in, you must do my work for me

https://pastebin.com/JGs4kz4z

here is my code

im trying to call the 2 functions at the same time (so http requests go out at the same time), but function 2 shouldnt output its response unless function 1 is already finished running...

the problem is, i have no idea how Promises work, and apparently i've just made it so function 2 doesnt get called at all until function 1 is done*

*i feel bad already pls dont worry about my bugs**

**unless... haha....

Here you go, fellow nerd

I think of promises of sort of like how callbacks were used: when the thing is done, it executes the ".then()".

"async" makes it really easy to follow the flow of stuff, so you don't need ".then()" all over the place and your code isn't all ugly.

Let me know if you have questions!

holy poo poo thank you, gonna give this a shot! i haven't used "await" either before but this definitely looks like good stuff

and vanilla js is always ftw :^}

Yeah, async/await are neato. I don't use them all the time because they're a bit more limited, but in a lot of cases they're just fine and make your code a lot easier to follow. Here's two ways to do the same thing:
JavaScript code:
function bar() {
  foo()
  .then((a) => {
    console.log(a)
  })
}
JavaScript code:
async function bar() {
  a = await foo()
  console.log(a)
}

Still getting the intuitive hang of it, but the code you provided is really great, thanks a ton man

got my 2 HTTP requests to start at the same time! which was my big goal

lowkey surprised that they are actually getting processed in parallel, even though i supposedly know that PHP creates new threads or w/e for each new process ...

man what a w00t day
