Mastering Angular 10: Essential Interview Questions and Answers

Understanding Angular: A Developer's Perspective

What is Angular?

Angular is a comprehensive platform and framework designed for creating dynamic single-page client applications using HTML and TypeScript. It is the successor to AngularJS and is often referred to as Angular 2 or later versions. Angular leverages TypeScript, which is a superset of JavaScript, offering additional features like static typing and object-oriented components. This framework is ideal for building both mobile and desktop applications with a focus on high performance and responsive design.

The Advantages of Choosing Angular

Angular is favored for its ability to create interactive SPAs with a range of powerful features:

• Two-way Data Binding: This feature synchronizes the model and the view, allowing changes in the model to instantly reflect in the view and vice versa.
• Modular Development: Angular organizes code into modules, making the codebase more manageable and facilitating lazy loading.
• Templating: Angular uses HTML to define the user interface, which is intuitive and less complex than JavaScript.
• RESTful API Handling: Angular simplifies the process of communicating with servers via RESTful APIs.
• Dependency Injection: This design pattern is integral to Angular, enhancing code modularity and reuse.
• Google's Support: Google's long-term support for Angular instills confidence in the framework's reliability and future.
• TypeScript: The use of TypeScript in Angular applications ensures higher security and helps catch errors early in the development process.
• Simplified Testing: Angular's design makes unit testing straightforward, with modules that can be easily manipulated and tested independently.
