async/await: A Modern Romance

Remember callback hell? Those pyramids of doom,
Where .then() and .catch() filled every room,
Indentation growing deeper with each nested call,
We promised ourselves we'd escape it all.

Then you arrived, async and await,
Two keywords that would seal our fate,
You made asynchronous code read top to bottom,
Like synchronous code, but you never fought 'em.

async function fetchData() {
  const user = await getUser()
  const posts = await getPosts(user.id)
  const comments = await getComments(posts)
  return comments
}

Look at that beauty! Sequential and clear,
No more callbacks nested, no more fear,
Error handling? Just try and catch,
Our code is now clean, a perfect match.

The old way haunts us in legacy code,
Those .then() chains, that heavy load,
But in new projects, you reign supreme,
async/await, you're the team's dream.

Some say Promises were fine on their own,
But you gave us syntax that feels like home,
So here's to you, syntactic sugar sweet,
Making async code a pure treat.
