How does async/await improve asynchronous programming?

Answer

Async/await simplifies asynchronous programming by making asynchronous code look and behave like synchronous code, improving readability and maintainability. Here's a basic example of how async/await is used:

<!-- BEGIN COPY / PASTE -->
        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);
            }
        }

        fetchData();
        <!-- END COPY / PASTE -->

Additional Comment:

The "async" keyword before a function declaration allows the use of "await" inside the function.
"await" pauses the function execution until the Promise is resolved, making the code easier to read.
Error handling is simplified with try/catch blocks, similar to synchronous code.
Async/await is built on top of Promises and does not block the main thread.
