What is Nodejs?
Node.js is an open-source, cross-platform JavaScript runtime
environment that allows developers to run JavaScript code on the
server side. It is built on the V8 JavaScript runtime engine, which is
the same engine that powers the Google Chrome web browser. Node.js
enables the execution of JavaScript outside the browser, facilitating
server-side development for creating scalable and high-performance web
applications.
Key features and aspects of Node.js include:
-
JavaScript on the Server Side:Node.js extends the use of JavaScript beyond the browser, allowing developers to use the same language for both client-side and server-side development. This unification of the development language can lead to improved productivity and code-sharing between the client and server components.
-
Asynchronous and Event-Driven: One of the defining characteristics of Node.js is its event-driven, non-blocking I/O model. This means that it can handle a large number of concurrent connections efficiently without the need for multi-threading.
-
NPM (Node Package Manager):Node.js comes with a package manager called NPM, which is one of the largest software registries globally. NPM allows developers to easily install, manage, and share third-party libraries and packages, enhancing the modularity and reusability of Node.js applications.
