I'm diving into JavaScript and recently started learning about asynchronous programming. I get that promises and callbacks are essential for understanding how asynchrony works. But in real-world applications, do developers still use promises, or has async/await taken over completely? I know async/await is essentially a wrapper around promises, which makes me wonder if there's still a reason to use promises directly, even with async/await being so popular.

Absolutely, promises are still crucial even with async/await. While the latter has made promise usage less visible, many APIs still utilize promises. You should be comfortable with the Promise API because it’s foundational to asynchronous JavaScript.
For the most part, yes! Async/await has become the go-to for handling asynchronous code, but promises are still heavily used in certain situations, like fetching data from APIs, so it’s good to know them.
Definitely! While async/await simplifies things, it's just a syntactic sugar for promises. So, if you're using async functions, you're working with promises regardless.
Async/await is built on promises, so whenever you use async functions, you’re actually using promises under the hood. Even if you're writing with async/await syntax, knowing how promises work is beneficial. For instance, you can use async without await if your scenario calls for it.
Yeah, async/await is just a nicer syntax for working with promises. They’re still relevant! You'll often come across methods like Promise.all() and Promise.race() in your coding, especially in async/await contexts.
