Node.js registers with the operating system so the OS notifies it of asynchronous I/O events such as new connections. Within the Node.js runtime, events trigger callbacks and each connection is handled as a small heap allocation. Traditionally, relatively heavyweight OS processes or threads handled each connection.
Express.js, or simply Express, is a back end web application framework for building RESTful APIs with Node.js, released as free and open-source software under the MIT License. It is designed for building web applications and APIs. [2] It has been called the de facto standard server framework for Node.js. [3]
It also uses various APIs to enable functionality such as native integration with Node.js services and an inter-process communication module. Electron was originally built for Atom [ 5 ] and is the main GUI framework behind several other open-source projects including GitHub Desktop , Light Table , [ 8 ] Visual Studio Code , WordPress Desktop ...
Deno and Node.js are both runtimes built on the V8 JavaScript engine developed by the Chromium Project, the engine used for Chromium and Google Chrome web browsers. They both have internal event loops and provide command-line interfaces for running scripts and a wide range of system utilities. Deno mainly deviates from Node.js in the following ...

[6] [7] [8] The V8 assembler is based on the Strongtalk assembler. [9] On 7 December 2010, a new compiling infrastructure named Crankshaft was released, with speed improvements. [10] In version 41 of Chrome in 2015, project TurboFan was added to provide more performance improvements with previously challenging workloads such as asm.js. [11]
Node-RED has gained traction in the industrial internet of things (IIoT) and edge computing sectors. [8] [9] [10] Node-RED's open-source nature and large community have led to the creation of over 4000 connectors [11] supporting a wide range of data sources and protocols such as Modbus, OPC-UA, Siemens S7, and MQTT.
