Modern JavaScript from the Beginning - Second Edition - Multiple Promises with Async and Await

The video tutorial covers the use of promises and async/await in JavaScript. It starts by explaining how promises work and introduces the async/await syntax for handling asynchronous operations. The tutorial demonstrates using async/await with a custom getData function and then transitions to using the fetch API for data retrieval. It also explores the use of Promise.all to handle multiple promises concurrently. The tutorial emphasizes that there are multiple ways to achieve the same result and encourages choosing the method that best suits the developer's needs.
