What are some effective asynchronous JavaScript techniques?

Some effective asynchronous JavaScript techniques include Promises, async/await, and callbacks. Would you like to dive deeper into any of these?

Can you explain how async/await works?

Sure! Async/await is syntactic sugar over Promises. You use the 'async' keyword before a function to make it return a Promise, and 'await' pauses the execution until the Promise is resolved.

What are the advantages of using async/await over callbacks?

Async/await makes your code cleaner and easier to read, avoiding callback hell. It also allows for better error handling with try/catch.

Can you give me an example of using async/await?

Absolutely! Here's a simple example:

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

This function fetches data from an API and handles errors gracefully.
