What is Ahead-of-Time (AOT) compilation?
Ahead-of-Time compilation is a process of compiling Angular templates at build time, instead of at runtime. This has several benefits, including performance gains, reduced application size, and better error checking. Ahead-of-Time compilation is a complex process, and it offers several options for configuring it.
What are decorators, and how are they used in Angular?
Decorators are design patterns to extend the functionality of a class. In Angular, decorators are extensively used to add metadata to classes. This metadata can configure the class's behaviour, resolve dependencies, compile the template, and perform other critical functions. Decorators are powerful and can create custom HTML tags, reusable components, and more.
What are the benefits of using Angular?
Angular offers several benefits that make it well-suited for building web applications. First, its two-way data binding makes it easy to keep the UI and the data in sync. Second, its dependency injection feature makes it easy to manage dependencies in an application. Finally, its modularity allows you to divide an application into smaller, more manageable pieces.”
What are the key features of Angular?
Angular is a powerful framework for building web applications. Some of its key features include two-way data binding, dependency injection, end-to-end tooling, and a templating system. These features make it very easy to use and extremely flexible, which is why it's so popular.”
What are single-page applications, and why are they popular?
Single-page applications (SPAs) are web applications that load a single HTML page and dynamically update the page as the user interacts with the app. SPAs are popular because they offer a smoother, more responsive user experience, similar to that of a native app. Angular is well-suited for building SPAs because of its powerful data binding and dependency injection features.”
What is data binding, and how does it work in Angular?
Data binding is to synchronize data between the model and the view. Angular offers two-way data binding, so changes made to the data in the model automatically reflect in the view and vice versa. This makes it easy to keep the UI and the data in sync, which can be very useful when building web applications
What are directives, and how are they used in Angular?
Directives are instructions that tell Angular how to render a particular piece of the UI. You can use them to add or remove elements from the DOM or to change the appearance or behaviour of an element. You can use directives in these applications extensively to give them more flexibility. They're powerful and can create custom HTML tags and reusable components.
What is the difference between AngularJS and Angular?
AngularJS is the original version of the Angular framework. Angular is the newer, updated version, and it offers a more modern, component-based approach to development, whereas AngularJS uses a more traditional MVC architecture. Both versions are popular choices for building web applications, but Angular is more powerful among the two.”
What is Dependency Injection
Dependency Injection (DI) is a design pattern used to implement IoC. It allows the creation of dependent objects outside of a class and provides those objects to a class through different ways. Using DI, we move the creation and binding of the dependent objects outside of the class that depends on them.
What is Angular?
“Angular is a front-end web development framework that makes it easy to build single-page applications. The framework helps developers create responsive, user-friendly web applications. It uses a variety of technologies, including HTML, CSS, and JavaScript, to power its applications. It also offers a variety of features, such as data binding and dependency injection, that can make development faster and easier.”
