Managing Child Processes in Node.js: Fork vs. Spawn

By

Node.js is renowned for its non-blocking I/O model, making it highly efficient for web servers and real-time applications. One way it achieves this is through child processes, allowing tasks to run in parallel rather than waiting in line. In Node.js, you can create child processes using various methods provided by the `child_process` module, among which `fork` and `spawn` are widely used. Understanding the differences and appropriate uses of these two methods is crucial for optimizing your Node.js applications.
