1. The Pros and Cons of Angular Development: All You Need to Know
Angular JS is a powerful JavaScript framework that has seen considerable growth in
recent times. In the US alone, it is used in the development of more than 71,508
websites. When considering this framework for your next project's front-end
engineering, it is important to assess its advantages and disadvantages. For companies
in the USA looking to use the Angular framework for their next front-end engineering
project, it is important to consider the pros and cons of Angular development. To provide
a better understanding of the framework, let's quickly review the basics. To get started,
let us quickly review the basics.
What is Angular?
Angular is an open-source framework managed by Google that has a large community
of contributors and is the first version of the Angular framework.
AngularJS and Angular
AngularJS app development services involve the development of applications with the
original version of AngularJS. This version is an MVC-based JavaScript framework that
uses directives to define and manipulate application components. Subsequent versions
of Angular, which are based on Google’s TypeScript, also offer component-based
architecture for more efficient and robust application development.
AngularJS provides an excellent opportunity for the development of single-page
applications. In addition, developers can benefit from its components which make
writing and refactoring code easier to use and maintain.
Two-way Data Binding
The Model-View-Controller (MVC) architecture was used to build the framework,
allowing for two-way data binding. This meant that any changes to the model would
result in an update to the view, reducing the amount of time developers had to spend

2. synchronizing the model and the view.
Big Community
One of the key reasons for AngularJS success was the abundance of tutorials and
training materials available, which made problem-solving simpler and quicker for web
developers. Furthermore, third-party tools and discussion forums facilitated this process.
The Dependency Injection
The concept of Dependency Injection is when code depends on each other. Whenever a
dependency is changed, the corresponding component also has to be altered. Angular
JS helps to break down the components and their dependencies, making the code more
reusable and easier to manage.
Directives
Angular JS enhanced HTML by introducing directives, which are attributes that modify
the DOM and allow developers to create interactive and rich content using HTML.
Cons of AngularJS
Now that you are aware of the benefits of AngularJS, let's look at some of its
drawbacks.
Performance
Dynamic apps have not always had satisfactory performance, leading to lagging issues
with larger SPAs.
Mandatory JavaScript Support
Additionally, many users have their JavaScript disabled, making it impossible for them to
access a dynamic web application.

3. Pros of Angular
Below are some of the advantages of developing applications with Angular:
Component-based Architecture
AngularJS Development Companies in USA have transitioned from the traditional
model view (MVC) architecture to a component-based structure for Angular 2 and above
versions. This enables better reusability of components throughout the development
process and a strict hierarchy of components, where each UI element on a particular
screen can be a component itself.
The hierarchical structure of components facilitates reusability in different areas of the
application. Additionally, the code is easily readable, allowing new developers to
understand it quickly. Moreover, the independent nature of components makes it easier
to conduct quality assurance on the smallest units. Finally, the decoupling of
components enables a smoother replacement and implementation process.
High Performance
What are the strong pillars that contribute to Angular's high
performance?
(i) Hierarchical Dependency Injection
Hierarchical dependency injection is an approach used in Angular 2 (and later versions)
which is much faster than its JavaScript predecessor. By decoupling components from
their dependencies, classes can receive them externally instead of being dependent on
themselves.
ii) Differential loading
Differential loading is a feature that was introduced in Angular 8, which helps to improve

4. overall performance by reducing the size of bundles and increasing loading speed for
browsers.
(iii) Angular Universal
Angular Universal is a service offered by Angular that allows applications to be rendered
on the server instead of the user's web browser. Google provides tools to enable pre-
rendering or re-rendering of the app with each user request.
(iv) Ivy renderer
The Ivy renderer, which is the standard compiler included in the Angular 9 update, is an
ahead-of-time (AOT) compiler that enables faster compilation and optimization of large
applications, thereby improving their performance.
Angular Elements and Directives
If you need to move between different settings, you can reuse your Angular component
by turning it into a DOM element. Furthermore, directives can be used to increase
HTML's capabilities and to add or remove elements from the DOM tree.
Backing by Google
Having the trust badge of Google, developers have been opting for the Angular
framework due to Google's long-term support (LTS) which ensures that the platform's
ecosystem will be backed and developed further to expand its market.
Huge Community
Angular's strength lies in the wide range of packages, plug-ins, and development tools it
offers. This makes it easier for developers to access help and simplifies the
development process if they get stuck.

5. Material Design Interface
Angular is leveraging material design components in order to improve the user
experience by creating an attractive and intuitive interface. Pre-built components in
Angular Material make it easier to integrate into existing projects.
Cons of Angular
Now that the advantages of Angular have been discussed, let's look at its drawbacks.
Time-consuming Migration from Angular to Angular JS
Migrating from Angular to AngularJS can be a lengthy and difficult process as the two
are vastly different. If running both versions at the same time, a thorough review must
be conducted and changes must be made to the new language, resulting in a much
heavier application.
Steep Learning Curve
Gaining a thorough understanding of Angular can be challenging, even for those
proficient in JavaScript. Working with components, modules, dependency injection,
templates, and other components of the framework requires diligent practice.
Furthermore, mastering RxJS, an asynchronous programming library, and TypeScript
can present an additional learning curve.
The Complexity of the Framework
The complexity of Angular makes it a powerful tool for web development, but
understanding it requires specialized expertise and support.
Conclusion
Having explored the advantages and disadvantages of the Angular framework
maintained by Google, you now have a better understanding of the features you can

6. make use of and the potential roadblocks you may encounter. The best practices
discussed in the Angular framework can help guide you in creating an enterprise-level
application.
