How does async/await interact with the event loop in JavaScript?
await pauses the async function and schedules the rest as a microtask. Control returns to the caller, who continues running synchronous code. When the stack is empty, the rest of the async function runs as a microtask.

Yes. async functions always return a promise. await pauses until a promise settles. The rest of the function after await runs as a microtask. async/await is syntactic sugar over promises.
Use try/catch around the await call. If the awaited promise rejects, the catch block runs. This is cleaner than .catch() with promise chains.
Start all promises at once and await them together with Promise.all: const [a, b] = await Promise.all([fetchA(), fetchB()]). This is much faster than sequential await for independent operations.
