What is the output of the following? “`js async function* generate() { for (const n of [1, 2, 3]) { yield await Promise.resolve(n * 10); } } (async () => { const results = []; for await (const val of generate()) { results.push(val); } console.log(results); })(); “`

What is the output of the following? “`js async function* generate() { for (const n of [1, 2, 3]) { yield await Promise.resolve(n * 10); } } (async () => { const results = []; for await (const val of generate()) { results.push(val); } console.log(results); })(); “`

Accepted Answer

The output of the code will be [10, 20, 30]. The generator function `generate` yields the result of each Promise resolved with n * 10. The `for await` loop then collects these values in the results array and logs it.
