What is Await?

In programming, particularly in asynchronous programming models (like those found in JavaScript with Promises or in C# with async/await), 'await' is a keyword that pauses the execution of an async function until a Promise or other awaitable object is resolved or rejected. It simplifies the syntax and structure of asynchronous code, making it read and behave more like synchronous code, while still operating asynchronously in the background. It avoids callback hell or complex Promise chaining. It is commonly used to handle asynchronous operations such as fetching data from an API, reading files, or performing other long-running tasks without blocking the main thread.
