Angular Study Guide


Angular is a powerful and versatile front-end web development framework developed and maintained by Google. As a platform that facilitates the creation of dynamic, single-page web applications, Angular offers developers a comprehensive set of tools, including a robust component-based architecture, two-way data binding, and dependency injection. This study guide aims to provide a structured pathway for both beginners and experienced developers to delve deep into Angular’s core concepts, best practices, and advanced features, ensuring a solid foundation for building modern web applications.

What is Angular?

Angular is a prominent open-source web application framework developed and maintained by Google, designed to assist developers in building dynamic, single-page web applications (SPAs). Rooted in a component-based architecture, Angular provides a platform that emphasizes modularity, allowing developers to create reusable components that can manage their own views, data, and logic. This architecture not only promotes code reusability but also makes it easier to manage and scale applications.

Beyond its architectural strengths, Angular stands out for its rich set of features, including two-way data binding, dependency injection, and a powerful templating engine. Two-way data binding ensures that the model and view are always in sync, simplifying the development process. Dependency injection, on the other hand, enhances modularity and code reuse by allowing components to request dependencies rather than hardcoding them. With its comprehensive toolset and strong backing from Google, Angular has become a go-to choice for developers aiming to build efficient, scalable, and maintainable web applications.

What are some differences between AngularJS and Angular?

AngularJS and Angular are both web application frameworks developed by Google, but they have significant differences in terms of architecture, syntax, and capabilities. Here are some of the key distinctions between the two:

Version and Terminology

  • AngularJS refers to the first version of the Angular framework, which is version 1.x.
  • Angular (without the “JS”) refers to versions 2 and above. It’s a complete rewrite of AngularJS and represents a shift in both design philosophy and underlying technology.


  • AngularJS uses a model-view-controller (MVC) architecture. Developers split their app into separate MVC components, and AngularJS manages the connections between them.
  • Angular employs a component-based architecture. Applications are broken down into reusable components, each with its own view and logic. This approach enhances modularity and facilitates easier maintenance and scaling.

Data Binding Data Binding:

  • AngularJS offers two-way data binding out of the box, which means that changes in the model automatically update the view and vice versa.
  • Angular also supports two-way data binding but introduces a unidirectional data flow for component interaction, improving performance by reducing unnecessary checks.
