What are async classes in JavaScript?

What are async classes in JavaScript?

Async classes in JavaScript allow you to define methods that return promises, enabling asynchronous operations.

Can you give me an example of an async class?

Sure! Here's a simple example:

class DataFetcher {
    async fetchData(url) {
        const response = await fetch(url);
        return await response.json();
    }
}

This class has an async method that fetches data from a URL.

What happens if I don't use 'await' in an async method?

If you don't use 'await', the method will return a promise immediately, and you won't get the resolved value until the promise is fulfilled.

Are there any limitations to using async classes?

Yes, async methods can only be used within async functions or classes, and error handling requires try-catch blocks.
