For smaller or less complex applications, the framework's full-featured nature may introduce unnecessary complexity. Moreover, the migration from AngularJS to Angular poses challenges, especially for large codebases, given the significant differences between the two versions.

<h2>Defining AngularJS</h2>

AngularJS is a JavaScript-based open-source front-end web application framework developed and maintained by Google. It promotes the development of active, single-page web applications by extending HTML with additional features and providing a framework for client-side MVC (Model-View-Controller) and MVVM (Model-View-ViewModel) architectures.
Moreover, AngularJS was released in 2010 to introduce the concept of two-way data binding. This allows automatic synchronization between the model and the view. Its modular design promotes code organization and reusability. Despite the following release of Angular, AngularJS continues to be used in some projects.

<h2>Features of AngularJS</h2>

<strong>Two-Way Data Binding</strong>

AngularJS pioneered two-way data binding, automatically synchronizing changes in the model with the view and vice versa. This simplified the <a href="https://www.ebizneeds.com/angularjs-development">angular web development</a> process and enhanced real-time user interaction.

<strong>MVC Architecture</strong>

AngularJS follows the Model-View-Controller (MVC) design pattern, splitting problems and promoting a modular structure. This makes it easier to manage code and collaborate on larger projects.

<strong>Directives</strong>

Directives extend HTML syntax, allowing developers to create custom HTML tags and attributes. This feature enhances code readability and promotes the creation of reusable components.
