• Display realtime data

# Disadvantages

• Complexity of your app increases, thus more development time and troubleshooting
• not handling ajax errors can mess up your app

• creates issues for screenreaders
• Larger code size means users have to download and unbundle more code before page is visible (bad for mobile)
