Businesses are continuously seeking for tactics to help them stand out in today’s digital era’s brutally competitive market. For any full-stack development studio to be successful, web and mobile apps have become a requirement as well as a useful marketing tool.

Among the greatest Javascript frameworks, Angular and Angular JS are the most widely used frameworks for web development. So what are the major differences between Angular vs Angular JS? Let’s have a quick look.


The Model View Controller (MVC) design is the foundation of the AngularJS architecture. Models are the primary components of an application that define its behaviour and manage its data, logic, and rules. On the other hand, components and directives are the foundation of Angular. Components are nothing more than pre-defined directives with pre-defined templates.


JavaScript is used by AngularJS. Angular 2 and its latest versions, on the other hand, use TypeScript. TypeScript is a superset of JavaScript that allows for static typing during development.

Dependency Injection

AngularJS and Angular both use dependency injection, but their implementations are very different. DI is used in many link functions, controller functions, and directive definitions in AngularJS. Declaratives, function Object() { [native code] } functions, and providers are used in Angular’s hierarchical dependency injection framework.

Expression Syntax

Angular is more spontaneous than AngularJS when it comes to data binding. When binding a property or an event in AngularJS, developers must use the correct directive. In the case of Angular, event binding is done with () while property binding is done with [].


AngularJS is significantly slower than Angular. According to the developers, angular applications can be up to five times faster than AngularJS applications if developed correctly.

Advantages of Angular

  • Angular is up to 5x faster than AngularJS because the data binding technique and component-based architecture are significantly superior in Angular.
  • Because Angular application components are self-contained and self-contained, they can be reused. It’s easy to replace, maintain, and measure the independent components.

AngularJS’s Benefits

  • AngularJS is a lot easier and faster to learn framework based on JavaScript.
  • Bi-directional data binding in AngularJS allows for faster and easier data binding without the need for developer interaction.
  • AngularJS allows for speedier prototyping and coding, resulting in a considerable reduction in development time.


In the battle for choosing Angular or AngularJS without a doubt, AngularJS wins. However, as applications become more complicated, it becomes necessary to employ the most recent version of Angular.

Having said that, it’s important to remember that learning Angular has a very steep learning curve. It requires a lot of effort to master it, especially since TypeScript is required as a precondition. On the other hand, Angular is unquestionably the way of the future. Google, for example, has switched to TypeScript.
