How do JavaScript Promises differ from async/await?

Thank you for posing such an insightful question. Understanding the nuances between Promises and async/await is crucial for any software engineering role, particularly for a position focused on JavaScript development. I'm excited to delve into these concepts, as they form a foundational aspect of building responsive and high-performing web applications. At its core, both Promises and async/await deal with asynchronous operations in JavaScript. Promises represent a significant evolution from callback-based patterns, providing a cleaner, more manageable approach to handling asynchronous tasks. A Promise in JavaScript is an object that may produce a single value some time in the future: either a resolved value or a reason that it's not resolved (e.g., a network error occurred). It allows us to attach callbacks rather than passing callbacks into a function. Let's clarify with an example...
