indentation should be consistent within a file; there are still places using 4-space indentation. If you're gonna change the indentation in so many places, you should change it everywhere in the file consistently (and you should use tabs because tabs >>>>> spaces)

Fixed identation.

await is unnecessary in a return statement; a Promise that resolves to a Promise is not resolved until that nested Promise is resolved:

/** @param p {Promise<unknown>} */
async function printAwait(p) {
	console.log(await p);
}

/**
 * @template T
 * @param p {Promise<T>}
 * @returns {Promise<Promise<T>>}
 */
async function nestPromise(p) {
	return p;
}

/**
 * @template T
 * @param p {Promise<T>}
 * @returns {Promise<T>}
 */
 async function awaitPromise(p) {
	 return await p;
 }

const p1 = new Promise(r=>r(5));
const p2 = new Promise(r=>r(p1));

// These are all equivalent
printAwait(p1); // outputs: 5
printAwait(p2); // outputs: 5
printAwait(nestPromise(p1)); // outputs: 5
printAwait(awaitPromise(p1)); // outputs: 5
printAwait(nestPromise(p2)); // outputs: 5
printAwait(awaitPromise(p2)); // outputs: 5

const p1 = new Promise(r=>r(5));
