Best Practices for Leveraging the Improved Build Performance of Angular 18 Projects

To maximize the benefits of improved build performance in Angular control flow, consider these best practices:

• Utilize Lazy Loading: Load modules only when needed to decrease initial load times.
• Enable Ahead-of-Time (AOT) Compilation: Precompile templates during the build phase for faster runtime performance.
• Optimize Imports: Ensure that only necessary modules and components are imported to minimize bundle size.

By incorporating these practices, developers can fully exploit the enhanced build capabilities of Angular custom directives for more efficient and rapid development cycles.

Component-Level State Management and Improved Developer Tooling

Angular 18 introduces robust support for component-level state management, making it easier to manage the state within individual components.
