The non-blocking I/O operations contribute to improved performance, making Node.js suitable for high I/O requirements. Additionally, the event-driven nature of Node.js simplifies code by eliminating the need for complex threading mechanisms.

JavaScript is actually incredibly efficient even though it’s only a single threaded.

I assume that it should mention about child process.
