How do JavaScript modules work with async functions?

Can you explain how JavaScript modules work with async functions?

Sure! JavaScript modules allow you to break your code into separate files, making it easier to manage. Async functions enable you to handle asynchronous operations, like fetching data, more elegantly. When you import a module that contains async functions, you can use the await keyword to pause execution until the promise is resolved.

What are the benefits of using async functions in modules?

Using async functions in modules helps improve code readability and maintainability. It allows you to write asynchronous code that looks synchronous, making it easier to follow the flow of your program. Additionally, it can help prevent callback hell and improve error handling with try/catch blocks.

Can you give me an example of an async function in a module?

Absolutely! Here's a simple example:

// myModule.js
export async function fetchData(url) {
    const response = await fetch(url);
    return await response.json();
}

You can then import and use this function in another module.

How do I handle errors in async functions?

You can handle errors in async functions using try/catch blocks. For example:

try {
    const data = await fetchData('https://api.example.com/data');
} catch (error) {
    console.error('Error fetching data:', error);
}
