What is an advantage provided by AngularJS 1.x?

Server-side view elements are automatically synchronized with their associated SQL models, and vice versa

Applications using AngularJS 1.x generally run faster than pure JavaScript applications

Data processing is offloaded more to Python on the server

Web server scripts will be encrypted and hard to break

The client will compute salt and pepper faster and send the encrypted text
