Node js is a server environment for execution of javascript code.
Javascript is a single-threaded application because of this we need a way to execute concurrent operations that is where googles v8 engine and libuv come to rescue.
libuv — a multi-platform support library with a focus on asynchronous I/O, written in C. It was primarily developed for use by Node.js, but it’s also used by Luvit, Julia, pyuv, and others. Node.js uses libuv to abstract non-blocking I/O operations to a unified interface across all supported platforms. This library provides mechanisms to handle file system, DNS, network, child processes, pipes, signal handling, polling, and streaming. It also includes a thread pool, also known as Worker Pool, for offloading work for some things that cannot be done asynchronously at the OS level.
