How to switch Node.js versions: A cross-platform guide for NVM and alternatives

Node Version Manager (NVM) is a versatile tool designed for managing multiple versions of Node.js, providing developers with the flexibility to switch between different versions as project requirements change, without affecting existing installations. It is especially useful for developers who work on projects requiring various Node.js versions, as it eliminates the need for manual version management, which can lead to errors and workflow disruptions. NVM is primarily used on Linux and macOS, but Windows users can utilize an alternative called nvm-windows, although a new tool named Runtime is in development to improve features like security and cross-platform support. Additionally, alternatives such as Volta, which offers per-project versioning and supports multiple operating systems, present other options for Node.js version management. The article discusses how NVM simplifies the process of installing, switching, and removing Node.js versions, providing practical examples and comparisons with other tools like Volta and direct downloads from the Node.js website.
