Async/await vs promises? If you’re a JavaScript developer, you’ve probably heard of async/await and promises. But what’s the difference between them? In this blog post, we will explore the differences between async/await and promises, and help you decide which one is right for you.
Async/await and promises are both ways to handle asynchronous code in JavaScript. Asynchronous code is code that doesn’t run immediately, but instead runs after a certain amount of time has passed. Promises are a way to handle asynchronous code that was introduced in ES2015, while async/await is a newer way to handle async code that was introduced in ES2017.

So, what’s the difference between async/await and promises? Let’s take a closer look.
Async/await is a syntax that makes it easier to write asynchronous code. With async/await, you can write async code as if it were synchronous code. This means that you can use async/await to write code that is easier to read and understand.
Promises, on the other hand, are a way to handle asynchronous code that allows you to chain multiple async operations together. This means that you can start an async operation, and then do something else while the async operation is running. Once the async operation is complete, you can then continue with the next async operation.
async/await or promises?
So, which one should you use? Async/await is a good choice if you want to write async code that is easier to read and understand. Promises are a good choice if you want to chain multiple async operations together.
If you’re not sure which one to use, async/await is probably a good place to start. Once you’re more comfortable with async code, you can then explore using promises.
