TypeScript serves as the foundation for the Angular website development programming platform. Angular is a framework that includes:

  • Web application development framework based on components
  • Many well-integrated libraries covering a broad range of functions, such as routing and forms management as well as client-server connection
  • Developer tools that aid in the creation, testing, and updating of your code

Angular is a platform that can be used to construct apps that range from small, one-person projects to large, multi-person ones. Updates are made as simple as possible so that you may take benefit of the most recent advancements with little effort. More than 1.7 million developers, library authors, and content contributors make up the Angular ecosystem.

The Angular website development CLI is an important concept to understand before diving into the Angular platform. In order to construct Angular apps, you should use the Angular CLI.

The template, styles, and class are the three primary pieces of a component in Angular. The AppComponent, for example, includes app.component.ts, app.component.html, and app.component.css. The logic, view, and styles are all separated in this framework, making it easier to maintain and expand the program.


A component testing file named app.component.spec.ts is also generate by the Angular CLI, but this article does not cover testing, so you may disregard that file.

It produces these four files in a directory with the name you provide whenever you develop a component.


TypeScript is use to build Angular website development. This means that any JavaScript that is legitimate is valid TypeScript, and vice versa. TypeScript makes it easier to type and has a more compact syntax than ordinary JavaScript, making it better for maintaining code and reducing the likelihood of errors.

An Angular application is made up of components. An HTML template, styling, and a TypeScript class are all included in a component.


Any logic your component need may be found in the class. In addition to functions and event listeners, this code may also include properties and pointers to other services. The class is store in a file with the name feature.component.ts, where feature is the name of your component’s corresponding ts class. So, you may have files with names such as header.component.ts, signup.component.ts, or feed.component.ts. As part of the Component() decorator, you provide information to the HTML and CSS that informs Angular where to locate them.

Using the app-item selector, you may access this component’s ItemComponent. Just like conventional HTML tags, selectors may be in use inside other templates. The template of a component is render when a selector is found in a template. In this lesson, you will learn how to create two different components and how to combine them.

Because of Angular’s component approach, applications are well-encapsulating and easy to understand. Components also make it easy to unit test your application and may enhance the readability of your code in general.


Styles from the application may be pass down to a component. css file and add its own styles to the mix. Directly in the @Component() decorator, you may define component-specific styles, or you can specify the URL to a CSS file.


Developers might use AngularJS to convert static HTML texts into dynamic content. AngularJS has been a popular option for online projects, particularly single-page applications, because to its comprehensive tools and MVC design. The AngularJS framework has been in use by some of the world’s most well-known firms, including PayPal, Upwork, and The Guardian. AngularJS is also in use by many others in their MEAN Stack. AngularJS, NodeJS, and MongoDB are all part of it.


The Angular team updated all of the code and added a slew of new capabilities to the reworked framework. Angular 2 is the first version of the framework without the suffix JS. A command-line interface and a component-based design are added to the framework in this edition. In the following part, we’ll learn more about Angular.

Angular’s performance has been steadily improve over time by Google. Angular provides 18 months of support for all major versions. The support is separate into active support and Long-term support.

The 13th version of Angular will do away with the View Engine, as the developers have noted. Ivy applications will still be able to utilize current libraries that require it. Angular, on the other hand, encourages library authors to begin the move to Ivy as soon as possible. The enhancements in the 12th edition are fairly comparable to the current version, Angular 11. Some of these include the ability to write regular lines more quickly and the fixing of bugs.
