Async/Await Syntax

In asynchronous programming, efficiently managing multiple tasks is essential for creating responsive and maintainable applications. While Promises provide a structured way to handle asynchronous operations, the async and await syntax simplifies this further.

Understanding async and await

The async and await keywords allow us to work with asynchronous code in a sequential way, making it easier to read and maintain. Here’s how each works:

• async: Declaring a function as async automatically returns a Promise. If the function returns a value, async wraps it in a Promise.

• await: Using await before a Promise inside an async function pauses execution until the awaited Promise resolves, allowing us to handle asynchronous operations in a synchronous-looking flow.

Example: Converting Promises to async/await

To illustrate, let’s first look at a Promise-based example and then convert it to use async and await for a cleaner syntax.
