Safety rules
Use the official page
Use nodejs.org for the install block.
Respect curl | bash
It means “download something from the internet, then run it.” Treat it carefully.
Do not chase random fixes
If something fails, stop and ask before pasting forum commands.
Final safe check
Type only the lines marked TYPE THIS. Do not type lines marked MAC REPLIES or NOTE.
TYPE THIS
node -vTYPE THIS
npm -vNOTE
Both commands should show version numbers after a successful install.
