Final answer:
The use of nvm, or Node Version Manager, is to manage multiple versions of Node.js for development purposes. It's essential for developers working on projects that require different Node.js versions or to test applications across versions.
Step-by-step explanation:
The term nvm stands for Node Version Manager. It's a tool used in software development, specifically for managing different versions of Node.js. Node.js is a runtime environment that allows you to run JavaScript on the server rather than in the browser.
The primary use of nvm is to install, uninstall, and switch between multiple versions of Node.js. This is particularly useful for developers who are working on multiple projects that may each require different Node.js versions. With nvm, they can easily switch to the appropriate version for each project without encountering version conflicts.
Additionally, nvm provides the flexibility to test applications on various Node.js versions to ensure compatibility, making it an essential tool for developers aiming to create robust applications. Nvm enhances productivity by simplifying the node version management process.
