# Install Node.js & NPM on Linux

**NODEJS**- Node.js is an open-source, cross-platform JavaScript runtime environment. It allows developers to create both front-end and back-end applications using JavaScript. Node.js runs on various platforms like Windows, Linux, Unix, and macOS, and it uses the V8 JavaScript engine. One key feature of Node.js is its asynchronous, event-driven model, which makes it memory efficient and enables non-blocking, concurrent execution of commands. It is widely used for building network programs such as web servers and benefits from a vast ecosystem of open-source libraries hosted on npm. Node.js architecture operates on a single thread, handling multiple event loops simultaneously. It offers modules for including functions in applications and supports fast data streaming without buffering. Node.js has gained popularity in web development due to its speed, scalability, and familiarity with JavaScript among developers.

**NPM**- NPM, which stands for Node Package Manager, is an essential component of Node.js. It serves as an online repository for thousands of open-source Node.js packages and provides a command-line utility for installing and managing versions/dependencies from these packages. NPM is automatically installed when running the Node Installer and can be used in any Node.js project. It offers convenient package installation, a vast library of third-party packages, scalability, better performance with non-blocking threads, cross-platform support, and enhanced reusability and maintainability. NPM plays a crucial role in the Node.js ecosystem by simplifying package management and enhancing the development process with its extensive library of packages
