Though best efforts are made to always use the Active LTS version of Node.js, this will not always be the case. For more details, please refer to the [Node.js release schedule](https://github.com/nodejs/Release#release-schedule).

 We recommend using the [Node Version Manager](https://github.com/nvm-sh/nvm) (nvm) since it is the easiest way to install and manage node for macOS, Linux, and Windows 10 using WSL2. See [our Development Tools guide](/docs/getting-started/devenv/README.md#development-tools) or the Nodejs site for additional installation instructions.
