Angular is a popular web framework that simplifies the process of building complex web applications. While it is designed for use with TypeScript and a variety of other development tools, Angular developers have a unique perspective on how to approach building vanilla JS apps.
One of the key principles that Angular developers keep in mind while building vanilla JS apps is the importance of modularity. This means that they focus on breaking down complex problems into smaller, more manageable pieces, and then building those pieces up into a larger solution. This approach is based on the idea that code should be reusable, easy to maintain, and easy to test.
Another key consideration that Angular developers keep in mind is the importance of data binding. Data binding is the process of linking the data in a web application to its corresponding visual elements, such as form fields, tables, or charts. This allows changes to be automatically reflected in the user interface without the need for manual updates. Angular developers often approach this by using a reactive programming style, where changes to data are propagated automatically through the application.
In addition to modularity and data binding, Angular developers also place a strong emphasis on component-based architecture. This involves breaking down an application into smaller, reusable components that can be easily combined to create more complex functionality. Components typically encapsulate a particular set of functionality, such as a login form or a navigation menu, and can be easily reused across an application.
Another key aspect of Angular thinking is the use of services. Services are reusable pieces of code that can be used throughout an application to perform specific tasks. For example, a service might be used to manage user authentication, or to retrieve data from an external API. Services can be injected into components as needed, making them highly flexible and reusable.
Finally, Angular developers often approach error handling and debugging with a systematic and structured approach. This involves using tools like the Angular CLI and browser developer tools to identify and resolve issues in code. Additionally, Angular developers often employ unit testing and end-to-end testing frameworks to ensure that their code is robust and error-free.
In conclusion, while Angular is designed as a full-featured web development framework, the principles of modularity, data binding, component-based architecture, service-oriented design, and systematic debugging can all be applied to vanilla JS applications as well. By adopting these approaches, developers can create more flexible, maintainable, and robust web applications that meet the needs of modern users.
