Answer 1

Node is flawless if you are having asynchronous tasks because java script will run these things by worker pool. But if you run CPU intense tasks (where you heavily use CPU ) Ex you have a billion users and you want to sort those people on name. Its quit a Intense tasks, and this is synchronous which will block other code from running.

So its not a good idea to use node for these kind of applications. Technically you can find alternatives to address those kind of tasks. The above example is better addressed in a Db. then passing that result is great.

In the same way avoid Intense task and keep your CPU cool for better performance
