Async JavaScript Explained — Callbacks, Promises & async/await | The Weekly Stack #11
en el canal de: The Weekly Stack
This is the one that breaks every junior dev — until it suddenly clicks.
In Session #11 of The Weekly Stack we go all the way through async JavaScript
from the ground up. The event loop, why JavaScript can't just wait, callbacks
and how they turned into callback hell, Promises and the .then() chain,
async/await and why it's the modern standard, fetch() with real HTTP requests,
try/catch error handling, and Promise.all for running things in parallel.
By the end of tonight, async code is never magic again. 🔥

WHAT WE COVERED
━━━━━━━━━━━━━━━━━━━━━━
00:00 Intro & check-in
→ The call stack & event loop — why async exists in a single-threaded language
→ Callbacks — where it started and why it got messy (callback hell)
→ Promises — pending, fulfilled, rejected — .then() and .catch()
→ async/await — the modern syntax, the rules, the gotchas
→ fetch() — real HTTP requests, response.ok, awaiting .json()
→ try/catch — error handling in async functions
→ Promise.all vs Promise.allSettled — parallel execution
→ Real-world refactor — callback hell → clean async/await
→ Games — Multiple Choice Dojo + Code Dojo: Async Edition
