NVM

NVM stands for Node version manager & as you might have guessed with name, its used to control Nodejs versions installed on our system. It is a command line utility, which allows us to use & switch between multiple versions of Nodejs. Node Version Manager (NVM) is a neat little bash script that allows you to manage multiple versions of Node.js on the same box. A version manager really helps to test our applications under different versions of the related software.
