Whenever the call stack receives asynchronous operations such as setTimeout, setImmediate, API calls, or file system operations, Node.js offloads these tasks to libuv.libuv is a C library that manages how asynchronous tasks should be executed. It interacts with the operating system’s kernel when needed to perform tasks like I/O operations efficiently.The event loop is what allows Node.js (via libuv) to coordinate and manage these asynchronous operations. The event loop has several phases where different types of tasks are processed. In total, there are six phases, though four are the main ones typically mentioned:Timers phase:Executes callbacks scheduled by setTimeout() and setInterval().…
