Why Angular? It's not a framework every programmer knows. Yes, Angular is one of the frameworks everyone knows, so it is one of the frameworks that every programmer must understand and grasp, especially novice programmers. So I write this article for those new to the profession or who have just switched to front-end programming. In the first article, I want to introduce the framework, history, advantages, and when and often used for Angular. So let's get started!

## So what is Angular?

Angular is an open-source framework. It is a JavaScript-based TypeScript development framework that eliminates unnecessary features and code to ensure lighter and faster applications.
Website designers can use HTML as a modeling language and extend the HTML syntax to convey application components. Furthermore, by using Angular, you also won't need to rely on third-party libraries to build dynamic applications.

Besides, Angular also allows you to create interactive single-page applications (SPA - Single Page Application) through attractive features like:
• Create templates (templates),
• Two-way binding,
• modularity,
• RESTful API (RESTful API access) handling and AJAX handling,
• dependency injection

## Angular development history
Google developed angular back in 2009. They aim to create a free and open-source framework that the community can use. First, it was called Angular 1 and then changed to AngularJS. Later versions were changed from Angular 2,3,4,5 to the current Angular 14. With each upgrade, Angular will be better fixed and improved to meet problem-solving needs. The complexity of modern platforms.

I can mention some outstanding features as Angular can create client site applications based on the Model-View-controller (MVC) framework, providing two-way data flow in the Document Object Model and having high compatibility

Since its inception, Angular has gained many users and supporters. In fact, according to Stack Overflow's 2021 developer survey, it's currently the third most popular web framework among professional developers.

## Why choose Angular over another Framework?
Understanding what Angular is not enough for you to choose for your next projects, let's find out the reasons why famous businesses or corporations choose to use Angular.

### Developed by Google
The first outstanding advantage of Angular is that Google supported and developed it. This worldwide most used search engine site provides Long-Term Support (LTS) for Angular to further expand the Angular environment.

Google applications all use Angular also they are considered stable. Angular users will have the opportunity to learn from Google's certified Angular experts.

### User interface
Angular uses HTML to define the user interface of the application. Compared to JavaScript, HTML is a less complex language. It is also a declarative and visual language with directives like ng-app, ng-model, ng-repeat, and form controls.

With the help of Angular, you don't need to invest time in program flows and decide what content to load first. Angular will handle what you ask. The front end has very HTML-friendly code by easily binds data to this platform.

Angular is a front-end platform that not only allows the development of modern applications but also allows the creation of high-end animations to enhance the user experience. Angular's API is so intuitive that developers can create complex videos and animations with low code.

Plus, with smart unit testing frameworks like Jasmine and Karma, you can fix your broken code at any time. Angular has more than 11 built-in testing modules to ensure error-free code.

### PWA and SPA – High Speed and Ultimate Performance
Angular Progressive Web Apps (PWA) is a cost-effective solution that allows websites to behave like mobile apps. PWA will reduce dependency on the network, greatly improving the user experience on the website.

Caching in a PWA is efficient and saves bandwidth whenever possible. This reduces the risk of serving outdated content. Furthermore, since it is a website, it can be optimized for SEO. 
It also helps to load the first page quickly and improves website performance on mobile devices, because AngularJS can easily run on any device, including mobile.

To summarize, the strengths of angular include:

### Code is clearer
Angular uses the TypeScript programming language, which is a superset of JavaScript. It compiles JavaScript but also eases the process of finding and eliminating common problems while coding.
This approach helps developers write cleaner and error-free code and ensures code quality, something that is helpful when investing in enterprise application development.

### Higher performance
Angular has hierarchical dependency injection, which is much better than AngularJS, where classes are not dependent on each other. It's quite oriented towards external sources, giving more performance to Angular mobile apps. 

### Better error handling
The latest version of Angular, Angular 14, also provides features such as improved error handling for @Output in situations where a property is not initialized.

### Seamless updates using Angular CLI
Angular CLI (Command-Line Interface) is easy to install and use, is newbie-friendly, offers innovative testing tools and simpler commands, and is supported by different engineers and platforms, making it easy to use. Can update even components with third-party dependencies.

### Material Design-like Interface

Angular provides pre-built material design via navigation elements, Orm controls, pop-ups, layouts, and data tables. This helps mobile app developers overcome the impact of Google Material Design on mobile app design and design a digital product that users need in the long run.

### Shorter development time
Angular allows developers to create web applications faster and more efficiently. This is due to the technical benefits that this framework offers, such as comprehensive documentation, the help and support of Google, and a large developer community.

### Safety
Angular is a popular and trusted platform because it has the backing of a large corporation like Google. Thanks to the community support – and because it is well maintained – Angular is considered by developers to be a reliable and trustworthy platform.

### Easy testing
Automated testing for each component of the entire Angular web application is very simple because it is divided into several parts. You also don't have to remember the order in which you should test. All you have to do is follow the “one-file-one-module” theory. The structure of the framework is divided into modules, and components, making your application ideal for unit testing. Each code unit is independently tested throughout Angular application development, giving you detailed quality control. 

### Cross-platform development
Angular is a cross-platform framework. Angular Progressive Web Application (PWA) solutions can run on multiple platforms and it widely used this framework in mobile applications. Because they can emulate native applications, more and more businesses are looking to develop cross-platform solutions with Angular.

Front-end developers have previously used a combination of Ionic and Angular for cross-platform development. But currently, the most popular mix is Angular + NativeScript.

### Cost-effective
Angular development is cost-effective for several reasons. First, it allows developers to use a single codebase to create a website with multiple versions. Second, they can use a variety of features and functions to create high-quality websites as quickly as possible. Finally, as mentioned above, you can also comfortably test Angular features, which reduces the risk of bugs at the next stage of development (and saves you a lot of time). As a result, developers can avoid testing all modules to detect and resolve any underlying issues. Bug-free apps leave users less frustrated. 

Entrepreneurs who choose Angular often do so because they desire a powerful, cost-effective user interface that allows them to win large audiences and generate money. That's because the framework provides everything entrepreneurs need.

## What is Angular usually utilized?

### Angular Progressive Web Applications (PWAs)
Imagine that your user is in an area with no network and wants to find a nearby supply store. Your application may not help them; even if it has all the necessary functions to help locate the store, it may not work if the user is offline. Every time the network goes down at any time during the life of the application, it will stop working.

Every time your user is disconnected, it can take a few minutes or longer for the initial site to load and set up.

One of the reasons why to create Progressive Web Applications was to avoid these network interruptions. PWA uses current browser technologies to provide a pleasant user experience, even if you enter an area without cellular transmission or an internet connection. PWAs use service workers to act as proxies that intercept network requests then they cache the response.

We can download PWAs on the client system. Thus, users can use the app even when their device is offline.

### Single-Page Applications (SPAs)
SPA is a suitable solution for website development. Users interact with the software application on a single page, which dynamically updates as they use it. SPAs are so well-known because they provide a better user experience (UX) compared with more traditional multi-page apps.

Angular's routing and data management make it easier to create SPAs while delivering staggering performance.

### Interfaces with Beautiful Animations
Incredible User Interface (UI) animations are becoming increasingly popular as a source of competitive advantage for web applications. If leveraged appropriately, you can make your app stand out and make a strong brand statement.

With Angular, you can create an attractive and intuitive interface that delivers a great user experience. That will help retain users because great UI and UX will drive users to want to return to your app. Given that Angular provides an easy-to-use module for user interactions, coding apps will also be fun for your development team.

### Enterprise Web Applications
No matter how large your project is, Angular will handle your application design now and as it scales. Businesses worldwide expect a durable enterprise web application with cutting-edge code that adheres to established standards.

The development of these applications must be highly optimized, business-oriented, and easy to understand, to support and accelerate the company's growth.

The benefits of using Angular for web development for enterprise applications are numerous, and the ability to achieve goals increased when translated into TypeScript. In addition, it has the aforementioned characteristics:
• Simple and easy maintenance 
• Autocomplete 
• Progressive restructuring 
• Fine-tune navigation 
• Code Reusability 
With all the information you have now, to guarantee that Angular is the right solution for you, let's put it together.

## In short, when should we use Angular?
Many companies are building digital products and services, but not all of them know when to use Angular. Considering your project's needs and desired user experience, you can resolve to use Angular.
If you are looking for a framework:
• Safe and reliable because of the supportive community and a major technology company (Google). 
• Allows easy testing. 
• Provides a vast library of verified third-party components. 
• Has high scalability potential due to the ease of adding new features. 
• Reduces development time as it is a cross-platform tool that allows you to code for many different platforms and provides simple, automated testing. 
• Moderately priced while giving the app a familiar feel. 
Deciding on an Angular project is a great choice.
