2. Download and install the Linux version of Google Chrome to debug JavaScript code for web apps.

wget https://dl-ssl.google.com/linux/linux_signing_key.pub -O /tmp/google.pub
gpg --no-default-keyring \
        --keyring /etc/apt/keyrings/google-chrome.gpg \
        --import /tmp/google.pub
echo 'deb [arch=amd64 signed-by=/etc/apt/keyrings/google-chrome.gpg] http://dl.google.com/linux/chrome/deb/ stable main' | sudo tee /etc/apt/sources.list.d/google-chrome.list
sudo apt-get update -y; sudo apt-get install -y google-chrome-stable
