What are the pros and cons of using Angular in web app development?

There are innumerous gadgets and web applications that have become an integral part of our life. Their computation power and performance multiplied by the programmers over the period. It was assumed that it involved a considerable amount of coding, but the fact is that the performance of these applications could be enhanced by a chunk of a few smart codes. But then, it would require a framework like Angular.

Angular is a framework and platform for building single-page client’s applications in CSS, HTML, and JavaScript/TypeScript. It is known to enhance a standard HTML and speed up an application’s responsiveness.

It has exceptional features like dependency injection, RESTful API handling, two-way data binding, modularization, and AJAX handling. Angular is a part of MEAN ( MongoDB, Express, Angular, Node.JS) stack and it is considered as one of the best frameworks for creating dynamic web applications.

Angular is used to develop desktop, native mobile apps, and web app development. Some popular websites built with Angular are iStockPhoto, Paypal, Netflix, Upwork, The Guardian, etc.

Pros of Angular in web development

• Angular MVC structure: The MVC structure helps to isolate application logic from the user interface layer and supports individual concerns. It makes the development process faster.
• Declarative user interface: Angular uses HTML to define the user interface of an application and is less complicated than Javascript. So developers have to invest less time in determining the program flows and what loads first
• Two-way data binding: It enables you to remove a lot of logic from the front-end. It helps developers to solve a lot of issues related to the website presentation architecture
• Lesser code: Developers have to write lesser code, as such; they don’t have to write their own MVC pipelines; they don’t have to put data into “view” mode manually; they can write directives with minimal integration and manipulate data on “view” level.
• Integration: Angular integration is pre-inbuilt into several frameworks, for example, Ionic, Wijmo, Telerik’s Kendo UI, etc. Hence, the integration of third-party features is easy with Angular.
• Hierarchical depending Injections: Angular uses dependency injection; thus, it makes code more clear, readable, and easy to maintain. The improved hierarchical depending injection decouples the actual components from their dependencies by running them parallel to each other. It allows Angular to build a separate tree of dependency injectors that can be altered without configuring the components
• Angular CLI: Angular provides support for command-line interface tools. These tools are used for adding components, testing, instant deploying, etc.
• Angular filters: The filter organizes data in such a way so that it is displayed only when certain criteria are fulfilled. Angular also supports custom filters
• Animation Support: Angular’s intuitive API enables the creation of complex animations and high performance with little code
• Compatible to a large number of code editors: Angular supports a large number of code editors
• No third party library dependency: With Angular, the developer does not have to rely on third-party libraries for dynamic web applications.
• Unit testing: It equips developers with amazing testing utility and ensures simplified unit testing.

Cons of Angular

• Complex SPAs: Due to their size building the SPAs (single page applications) can be inconvenient
• Not for gaming applications: It is not ideal for gaming applications or programs that require heavy maths or computation
• Steep learning curve: As compared to React or Vue, the Angular framework has a steep learning curve.
• Debugging the scope: Debugging the scope can be a difficult task
• Two-way data-binding: Though two-way data-binding is an advantage for web app developers but to some extent, it is considered as a complex process

Angular Js. is beneficial for web app development in many ways as it has a declarative interface, as well as it offers tow-ways data binding during the process. However, if you want to develop a gaming website, Angular Js might not be the right choice for it because it doesn't support heavy maths or computation. Also, debugging the scope can be a difficult thing wit Angular Js. A compared to other frameworks such as Vue or React, Angular has a very steep learning curve.
