how to install nodejs npm in linux code example

Example 1: linux install node

sudo apt install nodejs

Example 2: install node on linux

# 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

# Navigate to desktop to avoid problems with permissions
cd ~/Desktop

# Download the nvm script, but please note that new versions of nvm are
# released as the time pass, so you should always check the following link:
# https://github.com/nvm-sh/nvm#installing-and-updating
# to get updated info
sudo apt install curl && curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash

# 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")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"

# 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

# Please visit nvm github repo for more info: https://github.com/nvm-sh/nvm
