You may need a previous version of the nodejs while working on several projects, and others need a new version of nodejs, or to check the new NodeJs functionality, you need to instal the newest version of the nodejjs While working on several projects of NodeJs.
As on the same machine, we can only install one version of the nodejs, so it’s very painful to uninstall and install the new node version as per your project requirements.
To overcome this problem, we can use the Node Version Manager (NVM). NVM allows installing multiple node js versions on the same machine and switching between the required node js version.
