Cases when AngularJS does not work

1. Limited Browser Support: AngularJS may not work well with older browsers, especially Internet Explorer versions 8 and below. These older browsers may lack support for the necessary JavaScript features and APIs that AngularJS relies on, resulting in compatibility issues.
2. Performance Issues with Large Datasets: AngularJS may struggle to handle large datasets efficiently. When dealing with a significant amount of data, AngularJS’s two-way data binding and digest cycle can become slow and resource-intensive, leading to decreased performance.
3. Complex UI Interactions: While AngularJS provides a powerful framework for building user interfaces, it may not be the best choice for complex UI interactions. As the complexity of the UI increases, AngularJS’s declarative approach may make it harder to manage and debug the code.
4. SEO Limitations: AngularJS is a client-side framework that relies heavily on JavaScript to render the content. This can pose challenges for search engine optimization (SEO) since search engine crawlers may have difficulty indexing the dynamically generated content.
5. Learning Curve: AngularJS has a steep learning curve, especially for developers who are new to JavaScript frameworks. Its extensive feature set and complex concepts require time and effort to master, making it less suitable for small projects or projects with tight deadlines.

Pros & cons of AngularJS

6 Pros of AngularJS

• Improved productivity: AngularJS is designed to simplify the development process and make it more efficient. It provides a structured and organized framework that allows developers to build complex applications with less code and effort.
• Two-way data binding: One of the key features of AngularJS is its powerful two-way data binding. This means that any changes made in the user interface are automatically reflected in the underlying data model, and vice versa. This greatly simplifies the task of keeping the UI and data in sync.
• Modular architecture: AngularJS promotes the use of modular architecture, allowing developers to break down their applications into smaller, reusable components. This makes it easier to maintain and scale the application over time.
• Dependency injection: AngularJS has built-in dependency injection, which helps manage dependencies between different components of an application. This makes it easier to test and maintain code, as dependencies can be easily swapped or mocked.
• Extensibility: AngularJS provides a rich set of features and a flexible architecture that allows developers to extend and customize its functionality. This makes it possible to tailor AngularJS to meet specific project requirements.
• Large community and ecosystem: AngularJS has a large and active community of developers, which means there are plenty of resources, tutorials, and libraries available to help with development. This makes it easier to find support and solutions to common problems.

6 Cons of AngularJS

• Steep learning curve: AngularJS has a steep learning curve, especially for developers who are new to JavaScript frameworks. It introduces many concepts and features that may take time to fully grasp.
• Performance overhead: AngularJS adds some performance overhead due to its complex data binding system and other features. While this may not be noticeable for small applications, it can become a concern for larger, more complex projects.
• Limited SEO support: AngularJS relies heavily on JavaScript to render content, which can be a challenge for search engine optimization (SEO). Although there are workarounds available, it requires extra effort to ensure proper indexing by search engines.
• Compatibility issues: AngularJS has gone through several major version updates, which can lead to compatibility issues between different versions. This requires careful planning and testing when upgrading or integrating AngularJS with existing projects.
• Steep migration path: Moving from an older version of AngularJS to a newer version or migrating from another framework to AngularJS can be a complex process. It may require rewriting or refactoring existing code and can be time-consuming.
• Limited mobile support: While AngularJS can be used to build mobile applications, it is not specifically optimized for mobile development. There are other frameworks available that are better suited for mobile app development.
