What is the difference between async/await and promise chaining in JavaScript?
async/await is syntactic sugar over promises that makes code look synchronous and uses try/catch for errors. Promise chaining uses .then and .catch. async/await is more readable, has better stack traces, and works well with loops. Both are built on the same promise mechanism.

For most modern code, yes. async/await is more readable (looks synchronous), has better stack traces (easier debugging), and works well with loops (for...of with await). Use promise chaining for complex chains or when async/await is not available.
Promise chaining uses .catch. async/await uses try/catch around the await calls. try/catch is more familiar and cleaner, especially for multiple await calls in one function.
Yes. async/await is built on promises. You can await a .then chain, or use Promise.all with await. Example: const [a, b] = await Promise.all([fetchA(), fetchB()]).
