Solved: node update command

Sure, I can do that. Here is a rough draft:

Node.js is an open-source, cross-platform JavaScript runtime environment that permits developers to create all sorts of server-side tools and applications in JavaScript. Updating Node.js can be essential, particularly from a security perspective. It’s also important to get up to speed with the new features and improvements that come with each update. To solve this updating issue, we can use the node update command. Below is a solution to this scenario.

In order to update NodeJS, you may use **Node Version Manager (NVM)**. NVM is a command-line tool specifically built to manage multiple active Node.js versions.

// Installs the latest version
nvm install node 

// Use the latest version
nvm use node 

//To reinstall packages from previous version
nvm reinstall-packages v.13.9.1 

Working Principle of Node Version Manager (NVM)

NVM operates on any POSIX-compliant shell, although it needs to tweak your shell profile to work correctly. It permits a developer to install multiple Node.js versions, designating/switching among them with ease.

NVM seeks to alleviate the difficulties involved in managing and coordinating Node.js versions with the purpose of developing, testing, and enjoying more complex JavaScript programming.

The code listed above demonstrates the use of NVM, starting by installing the latest available node version and then activating it for use. If there are any packages installed under a previous version that you need to keep, the third command allows you to reinstall those packages.

Exploring npm (Node Package Manager)

The **npm** (Node Package Manager) is the official packet manager for Node.js. As part of every Node.js installation, npm helps in package installation, version management, and dependency management, which are key aspects in modern web development.

A **package.json** file in your app directory outlines all the dependencies of your project. You can add packages as a dependency by using the command ‘npm install ‘. Similarly, to delete a package, you can use ‘npm uninstall ‘.

An appreciable aspect of npm is the wide repository of JavaScript tools and the ability to manage multiple versions of code and code dependencies, which makes it easier for developers in terms of collaboration and deployment.

So, in the context of Node.js, keeping your system updated with NVM and understanding how to properly use npm can help you create, maintain, and deploy your JavaScript applications in a more efficient, manageable way.
