Angular Interview Practice

What is the result of using a framework that requires no need for a compiler, as is the case with Angular?

1. Increased complexity in code maintenance

2. Better performance and faster rendering

3. Reduced flexibility in component structure

4. Increased dependency on third-party libraries

The correct answer is: Better performance and faster rendering

Using a framework that does not require a compiler, like Angular, leads to better performance and faster rendering because it allows for more effective management of the application's structure and its interaction with the browser. In Angular, components and templates can be written in a way that the framework can directly use them. This reduces the overhead associated with compilation processes, which can slow down development and runtime. The absence of a compilation step can enhance the loading time and execution speed of an application because the framework can optimize how it interacts with the Document Object Model (DOM) upon initial load and subsequent updates. This efficiency is particularly important for larger applications where performance is crucial for user experience. Moreover, Angular’s use of Ahead-of-Time (AOT) compilation, when employed, yields similar benefits by pre-compiling components and templates, which also contributes to faster rendering in production. Thus, when a framework eliminates the need for a runtime compiler, it streamlines the process of rendering views and handling data changes, ultimately resulting in improved performance.
