Fortunately, there are many version managers to choose from, and this article will introduce the two most popular version managers: nvm and n.

Change Node.js version using nvm

nvm (Node Version Manager) is one of the most common Node.js version managers. It makes it easy to download, install, and use any version of Node.js. To change the Node.js version using nvm, follow these steps:
