A few days ago, I watched an interesting video on YouTube about Broken Promises that James Snell introduced.

You can find out some great examples that have introduced in the video from his repository.

According to what he said, we should not wrap purely synchronous code in a promise. And if we absolutely need a function to return a promise then resolve the promise synchronously by using Promise.resolve() method. Importantly, he also pointed out that run your code synchronously and save yourself the trouble of all those additional promise allocations.

After finished watching the video, I've looked into my code. And wonder what if I've done something similar as he mentioned in the clip.

Let me show you some examples.

Here's an async function that waits for promises to be resolved.
