What happens if you use await inside forEach in JavaScript?
forEach does not await the async callback. The loop finishes immediately, and the async callbacks run in parallel in the background. Use for...of for sequential await or Promise.all with map for parallel.

1, 3, 2. Code before await runs synchronously (1). await pauses the function and schedules the rest as a microtask. Code after the foo() call runs next (3, sync). Then the rest of foo runs (2, microtask).
Yes. If you return a value, it is wrapped in Promise.resolve. If you throw, it becomes Promise.reject. If you return a promise, it is returned as-is.
No. await pauses the async function and yields control to the caller. The caller continues running synchronous code. The rest of the async function runs as a microtask when the awaited promise settles.
