Updated on 09th May, 23 183 Views

Typescript is a type of open-source-general programming language developed and maintained by Microsoft. It is also called a superset of JavaScript because of its similarity with it and can transcompile to JavaScript source code. Before learning about Angular you should be experienced with typescript and command line interface (CLI). Also, if you want to start learning Angular, go through the concepts of HTML, CSS, and JavaScript.

If you are done with the above-mentioned tech let’s quickly check out the points to be discussed in this blog.

What is meant by Angular?

What is meant by Angular?

In a nutshell, it is a type of web framework that is used to create efficient single-page web applications from scratch. Angular and its components are built on the typescript. As Angular works on various types of components we also call Angular a component-based framework.

  • The major purpose for developing Angular was to find an alternative to Angular.Js.
  • It is an upgraded version of the same. Its architecture depends on NgModules which provides a structure for the associated commands and different components of Angular.
  • Angular is capable of developing both single developer-based applications as well as organizational-based applications sophisticatedly.
  • Angular also provides platforms for other types of technologies to be built upon. Applications developed on Angular are seen to be highly scalable.

Why should we consider Angular?

Why should we consider Angular?

It’s been quite a while since Angular was published since its first release there are a lot of updates have taken place. Because of these changes, it is still the to-go language for developers. 

Consider the below-mentioned points for which Angular is still in demand:

  • Angular is well documented from the beginning and it is still maintained to date by Google and associated community members.
  • It is a typescript-based framework, has a rich library source, and is very similar to javascript.
  • Angular has extended support from HTML which helps in better development of different components.
  • JavaScript code generation is possible, the generated code is highly optimized and robust.
  • The creation of templates is possible in Angular, this promotes code reusability and speeds up the development process.

Different Versions of Angular

Angular was first introduced in 2009 by Miško Hevery as an open-source framework. The framework was introduced for changing the way enterprise softwares were developed. Since then many contributors including individuals and various tech giants have contributed to the language.

  • Angular 1 also known as AngularJS was the first stable version to be published and was very efficient in developing single-page web applications.
  • Angular 2 is considered the remake of the version of AngularJS, it laid the foundation of modern-day Angular, with major bug fixes and mobile compatibility made available.
  • Angular 3 was never released by the organization, directly Angular 4 was released with minor bug fixes and improvements.
  • Angular 5 was the version of Angular that brought about several significant modifications, including the introduction of the DOM and API concepts.
  • Following each other, versions of Angular 6, 7, 8, 9, and 10 were released with small enhancements and bug fixes. The most recent version of Angular that we utilize right now is 11.

Now we know of different versions of Angular and its origin, let’s check out the strong architecture of Angular for which Angular is still in demand.

Architecture of Angular

Architecture of Angular

From online financing to healthcare almost every domain is covered. Web applications built on Angular are everywhere and making our lives easier over the web. Ever wondered how Angular does it? The answer to this question is strong architecture.

Let’s check out the basic terminologies associated with the architecture of Angular:

  • Modules: Modules in Angular refer to the elements where we can apply the bootstrap-like mechanism for the launch of the application. For example root module and named AppModule.
  • Components – Angular components are the classes where all the data and actual logic of the code are defined for the application.
  • Templates – Here templates bind up the markups of Angular to the HTML to identify the HTML elements before their display.
  • Metadata – Metadata refers to the information which tells the process of a class.
  • Services – It is a type of class that is created for the data which is not associated with any view but has to be shared through the different components of the code. 
  • Dependency Injections:
    • It is a feature of Angular that helps to maintain the component class efficiently.
    • It facilitates the tasks like input validation, fetching of the data, logs directory, etc.

Features of Angular

Features of Angular

Here are the reasons why Angular is still popular among developers:

  • The Angular code is transpiled as it works on typescript, which makes Angular more flexible.
  • Code writing is crisp, concise, and saves a lot of time for development.
  • Testing the application is easy to do as compared to its alternatives.
  • Angular has a very strong architecture it has a fully implemented MVC framework. This enables the applications to have smooth bi-directional data flow.
  • It is easy to develop customized components in Angular as it has an option for bootstrap grid templates.
  • It is a type of cross-platform framework that can communicate with different types of browsers.

Difference between Angular and React

Difference between Angular and React

Let’s examine the differences between the two technologies that are being used to construct web applications. Go through the below-mentioned pointers thoroughly to get a glimpse of the difference that Angular and React possess.

React can be distinguished by the following:

  • It is a type of library built on JavaScript that was created before Angular and is only involved in the building of user interfaces.
  • React only provides data binding in one direction.
  • It provides developers with extra alternatives during the development process.
  • It has a greater number of stable versions than Angular, hence its documentation loads more quickly.
  • React may be used to create hybrid applications as well as native web applications.

Career Transition

Differentiating pointers for Angular:

  • It is a type of full-fledged framework that is used for the development of single-page applications.
  • It supports bi-directional data binding which is two-way communication.
  • Developers have limited options during the process of development.
  • It is stable but it is constantly developing which becomes a pain for users to switch to different syntax after every new release.
  • Angular supports complete dependency injection which allows components to have different life cycles.
