Angular Interview Practice

What does the 'bootstrap' property in an Angular module determine?

1. The services that are available throughout the application

2. The components that will be created and inserted into index.html

3. The modules that the application will import

4. The directives that can be used in the application

The correct answer is: The components that will be created and inserted into index.html

The 'bootstrap' property in an Angular module is crucial as it specifies which components of the application are bootstrapped or initialized when the application starts. Essentially, these are the components that Angular creates and inserts into the index.html file, forming the root part of the component tree. When the application launches, the Angular framework looks at the 'bootstrap' array in the module metadata and instantiates the defined components, thereby rendering them on the page. This mechanism is integral to Angular's architecture because it establishes the entry point for the application and lays the groundwork for its component interactions and lifecycle management. The components listed in the 'bootstrap' property are responsible for rendering the UI and handling initial application logic. Understanding the bootstrapping process is essential for an Angular developer since it directly influences how components are loaded and displayed to users.
