4. Automatic Inlining of Fonts: Angular 11 introduced automatic font inlining, which means that font files used in the application are now automatically added to the CSS bundle, eliminating the need for separate font requests.
5. Differential Loading by Default: With Angular 11, differential loading was made the default setting for production builds. This means that modern browsers receive smaller and more efficient ES2015+ JavaScript bundles, while older browsers get ES5 bundles, providing better performance and compatibility.
6. Improved ESLint Support: Angular 11 enhanced its support for ESLint, a popular JavaScript linter, providing developers with more options for static code analysis and improving code quality.
7. Performance Improvements: Several performance improvements were made in Angular 11, including optimized type checking for templates, leading to faster builds and reduced memory usage.
8. New Date Range Picker: Angular 11 introduced a new Date Range Picker component, making it easier for developers to select date ranges in their applications.
9. Updated Language Service Preview: The Language Service, used by various IDEs and editors to provide code intelligence and autocompletion, received updates to improve the development experience.

Remember that Angular is a rapidly evolving framework, and newer versions might introduce more features and enhancements. To get the latest information, I recommend checking the official Angular website or the release notes of the specific version you are interested in.

Angular 9 New features

1.Ivy Renderer:  The most significant change in Angular 9 was the introduction of the Ivy rendering engine as the default renderer. Ivy is a new, backward-compatible compilation and rendering pipeline that replaces the older View Engine.

Ivy brings several benefits, including:

• Smaller Bundle Sizes: Ivy offers improved tree-shaking capabilities, which means that unused code is removed from the final bundle, resulting in smaller file sizes. This can significantly reduce the size of the JavaScript bundles delivered to users, leading to faster load times.

• Faster Compilation: Ivy is more efficient in compiling Angular templates and generates faster code compared to the View Engine. This leads to faster application start up times and overall improved performance.

• Improved Debugging and Build Times: Ivy provides better debugging support with enhanced error messages and source maps, making it easier to identify issues during development. Additionally, Ivy's incremental compilation allows for faster rebuilds during development.

 

2. Lazy Loading of Components: Angular 9 introduced the ability to lazy load individual components, allowing developers to optimize application loading times. Lazy loading means that certain components and modules are loaded only when they are required, not during the initial application load. This is particularly useful for large applications where loading everything at once can slow down the initial page load.

Lazy loading can be achieved using the componentFactoryResolver from Angular’s core library or by using Angular’s built-in RouterModule to set up lazy-loaded routes.

3. Optional Strict Mode: Angular 9 introduced strict mode, an optional configuration that enables a more stringent development environment. When strict mode is enabled, the compiler applies stricter type-checking rules, enforces best practices, and catches more errors during development.

With strict mode, developers are encouraged to write cleaner, more robust code and catch potential issues at build time, rather than at runtime. This can lead to more maintainable and stable applications.

4. Improved Internationalization (i18n): Angular 9 made significant improvements to its internationalization (i18n) capabilities, making it easier to create and maintain applications in multiple languages. The i18n extraction and translation process were streamlined and enhanced, allowing developers to generate translated versions of their application more easily.

The improvements in i18n make it more convenient for international teams to collaborate on translating the application's text, ensuring a smoother user experience for users from different language backgrounds.

5. Angular Language Service: The Angular Language Service, introduced in Angular 9, provides better code intelligence and autocompletion for Angular templates within popular code editors like Visual Studio Code.

The language service understands Angular templates and provides intelligent suggestions and hints as you type, helping developers write code faster and with fewer errors.

6. Updated Dependencies: Angular 9 updated several underlying dependencies to their latest versions, including TypeScript 3.7 and RxJS 6.5. Keeping dependencies up to date ensures that Angular applications stay current with the latest features, bug fixes, and performance improvements in the underlying technologies.

7. Router Updates: The router in Angular 9 introduced various improvements and bug fixes, enhancing the overall navigation experience in Angular applications.

In summary, Angular 9 brought significant improvements in performance, build times, and developer experience. It introduced the Ivy renderer as the default, which improved the overall application performance by reducing bundle sizes and enhancing compilation. The update also focused on making Angular applications more maintainable with strict mode, better internationalization support, and improved tooling like the Angular Language Service.
