Yep, even AngujarJs is still being used for big companies. For example, there are companies using it:

• Paypal community: https://www.paypal-community.com/t5/PayPal-Community/ct-p/en
• Microsoft support page: https://support.office.com/
• Google pages (of course, they made it hahahaha): https://startup.google.com/ https://express.google.com/u/0/
• Microsoft Customer page: https://customers.microsoft.com/

This list can go veryyyy large. Here is a page with all of them (well maybe the majority of them):
