Async & Await

The video tutorial introduces the async/await feature in JavaScript, part of the ES7 standard, and demonstrates its implementation in Chrome. It covers creating basic functions with async, using async with promises and setTimeout, handling errors in async functions, and applying async/await with the fetch API. The tutorial emphasizes the benefits of async/await in simplifying asynchronous code, making it more readable and manageable compared to traditional promise chaining.
