AngularJS employs MVC, or Model-View-Controller, architecture, in which the Model holds business logic, the Controller processes data, and the View displays data from the Model.  Components replace controllers in Angular. Components are just directives that have a preset template.  AngularJS makes use of the JavaScript language, which is a dynamically typed language.  Angular employs TypeScript, a statically typed language that is a superset of JavaScript. Angular delivers greater speed when constructing bigger apps by employing a statically typed language.  Mobile Assistance  AngularJS does not support mobile devices.  All prominent mobile browsers support Angular.  Structure  In the case of AngularJS, the process of maintaining code gets onerous while constructing larger projects.  Because Angular gives a better framework, it is easier to maintain code for larger apps.  Syntax of Expressions  A developer must remember the correct ng-directive for binding an event or a property while creating an AngularJS application. In Angular, property binding is done with the "[]" attribute, while event binding is done with the "()" attribute.
