Angular is a highly-recommended framework for building dynamic web applications. Its MVC architecture simplifies UI development by eliminating unnecessary code, like getters and setters. Additionally, Angular is written in TypeScript, with additional language options. Its data binding and directive system allows you to create less code by organizing application functionality into modules. And, you can use lazy loading to optimize performance. In this article, we’ll examine two of the most popular directives and their respective functions in AngularJS.
Angular event binding works similar to property binding. When you specify the event you want to trigger, you use the (event) keyword to describe it. Any valid event type, such as a click, can be binded to a component’s data or template. Event handlers are member functions of a component class, and a parenthesis tells Angular to bind the event to the appropriate assignment.
Angular’s modular architecture also facilitates division of labor among developers. Developers can increase their productivity by distributing their work across different modules. Inconsistent coding can cause delays and elevated costs. With a common framework, it’s easier to create a consistent code base, and use templates and predefined code snippets to make the development process faster and easier. In addition to speeding up development, Angular allows you to create a more maintainable and easier-to-use site.
Every Angular application has at least one component. This root component connects the component hierarchy to the DOM, while each component defines a class and HTML template. Angular uses a decorator called @Component() to mark a class as a component and provide component-specific metadata (more information). This is useful if you need to associate your component with a particular element. Then, use a selector to identify a particular view with a component.
