# It's a good idea to use NVM (Node Version Manager) if you want to install
# Node.js on Linux because it allows you to install many versions of Node
# simultaneously and switch between them easily

# You need to check whether nvm has been added to the PATH or not
# So you should execute the command
nvm --version
# IF IT HASN'T BEEN ADDED TO THE PATH, THEN MAKE SURE TO EXECUTE THESE COMMANDS:
export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"

# To install the latest version of node, use the command:
nvm install node
# You don't need to worry about npm installation as nvm automatically
# installs it alongside node
