It's recommended that you install the latest even numbered node, since:
You should always use even-numbered versions marked LTS that says “Recommended for Most Users” on the download page.
and:
After six months, odd-numbered releases (9, 11, etc.) become unsupported, and even-numbered releases (10, 12, etc.) move to Active LTS status and are ready for general use.
Is there a way (preferably a one-liner) to install the latest even numbered node without having to even look it up? (yeah, that's lazy, but it avoids any chance of human error, and also allows docs to remain up to date for years, since something like nvm install 16 will require updating in the future).
nvm install --lts is how you do it. Here are the docs for even more fun details.
