Laravel 8 first introduced HTTP request pooling, thanks to a contribution from Andrea Marco Sartori. This allows developers to write code which will execute any number of HTTP requests concurrently. Under the hood, this is made possible thanks to the async request functionality of Guzzle and cURL’s multi handler functionality.

I love this pattern; and it works for any promise, with a bit of setup pic.twitter.com/kvsHU6zmpd

Tip: With async/await, you can run multiple async operations in parallel. How? Put the await statements on the same line! Works like promise.all. https://t.co/0aoAAvILmE#javascript pic.twitter.com/RMrXKp8D7V

On his blog Mathias Bynens explains the differences under the hood between async/await and vanilla promises.

The fundamental difference between await and vanilla promises is that await X() suspends execution of the current function, while promise.then(X) continues execution of the current function after adding the X call to the callback chain. In the context of stack traces, this difference is pretty significant. ... Enable JavaScript engines to handle stack traces in a more performant and memory-efficient manner by following these recommendations:

• Prefer async/await over desugared promises.
• Use babel-preset-env to avoid transpiling async/await unnecessarily. ...

In the JavaScript world promises are a great way to deal with stuff that needs to happen asynchronously. But there's also another new way to go about it: async/await.

In case you missed it, Node now supports async/await out of the box since version 7.6. If you haven’t tried it yet, here are a bunch of reasons with examples why you should adopt it immediately and never look back.

For those who have never heard of this topic before, here’s a quick intro

• Async/await is a new way to write asynchronous code. Previous options for asynchronous code are callbacks and promises.
• Async/await is actually built on top of promises. It cannot be used with plain callbacks or node callbacks.
• Async/await is, like promises, non blocking.
• Async/await makes asynchronous code look and behave a little more like synchronous code. This is where all its power lies.

Q: What is the difference between these four promises?

doSomething().then(function () {
  return doSomethingElse();
});
doSomething().then(function () {
doSomethingElse();
});
doSomething().then(doSomethingElse());
doSomething().then(doSomethingElse);

</div>
