Dahl presented Node.js, which combined Google 's V8 JavaScript engine, an event loop, and a low-level I/O API. The project received a standing ovation. In 2011, a package manager was introduced for Node.js library, called npm.

Micrograph of a mesenteric lymph node with adenocarcinoma. Lymph nodes may become enlarged due to an infection, tumour or inflamed due to leukemia. This increase in size is primarily due to an elevated rate of trafficking of lymphocytes into the node from the blood, exceeding the rate of outflow from the node.

Node.js is an open-source, cross-platform runtime environment for developing server-side web applications. Node.js applications are written in JavaScript and can be run within the Node.js runtime on OS X, Microsoft Windows, Linux, FreeBSD, NonStop, IBM AIX, IBM System z and IBM i. Its work is hosted and supported by the Node.js Foundation, a collaborative project at Linux Foundation.

Just because Node is designed without threads, doesn't mean you cannot take advantage of multiple cores in your environment. You can spawn child processes that are easy to communicate with by using our child_process.fork() API.

A lymph node is an oval-shaped organ of the lymphatic system, distributed widely throughout the body including the armpit and stomach and linked by lymphatic vessels. Lymph nodes are major sites of B, T, and other immune cells.

Node.js was invented in 2009 by Ryan Dahl and other developers working at Joyent. Node.js was created and first published for Linux use in 2009. Its development and maintenance was led by Dahl and sponsored by Joyent, the firm where Dahl worked.

Each lymph node is surrounded by a fibrous capsule, and inside the lymph node the fibrous capsule extends to form trabeculae. The substance of the lymph node is divided into the outer cortex and the inner medulla.

Node simply enters the event loop after executing the input script. Node exits the event loop when there are no more callbacks to perform. This behavior is like browser JavaScript -— the event loop is hidden from the user. HTTP is a first class citizen in Node, designed with streaming and low latency in mind. This makes Node well suited for the foundation of a web library or framework.

As an asynchronous event driven framework, Node.js is designed to build scalable network applications. In the following hello world example, many connections can be handled concurrently. Upon each connection the callback is fired, but if there is no work to be done Node is sleeping.

Node.js is event-driven, but most web servers are thread-based.York explains how Node.js works: You use your web browser to make a request for /about.html on a Node.js web server. The Node.js server accepts your request and calls a function to retrieve that file from disk. While the Node.js server is waiting for the file to be retrieved, it services the next web request.
