From Java To Node.js
This document compares Java and Node.js, highlighting key differences. Node.js is single-threaded and non-blocking, using callbacks. This allows Node.js to handle more requests with fewer resources than Java, which is multi-threaded and blocking. The document recommends considering Node.js due to its benefits of higher performance and lower memory usage compared to Java.
